Peacock’s psychological crime thriller has assembled a notable lineup of Hollywood performers, with the good daughter cast led by Rose Byrne, Meghann Fahy, and Brendan Gleeson. Based on Karin Slaughter’s bestselling novel, the six-episode drama follows two sisters whose lives remain shaped by a devastating family tragedy. A new violent incident in their Georgia hometown brings unresolved memories, complicated relationships, and disturbing questions back into their lives.
The series premiered on November 12, 2026, with all six episodes becoming available on Peacock in the United States. Rose Byrne portrays Samantha Quinn, while Meghann Fahy plays her younger sister, Charlotte Quinn. Brendan Gleeson appears as their father, Rusty Quinn, and Olivia Williams portrays their mother, Harriet Quinn.
The supporting ensemble includes Michael Dorman, Jake McDorman, Paula Malcomson, Harper Steele, Shayna Benardo, Audrey Grace Marshall, and Drew Cheek. Together, these performers bring the Quinn family and the surrounding Pikeville community to life.
The adaptation places considerable attention on the relationships between its characters. Instead of treating the central crime as an isolated event, the story explores how an earlier tragedy continues to affect the people involved years later.
What Is Peacock’s The Good Daughter About?
The Good Daughter is a psychological thriller based on Karin Slaughter’s 2017 novel. Its central characters are Samantha and Charlotte Quinn, two sisters who experienced a traumatic event during their childhood.
Their family lived in Pikeville, Georgia, where their father, Rusty Quinn, worked as a defense attorney. Their lives changed dramatically after a violent home invasion left the family dealing with devastating consequences.
The sisters eventually followed different paths. Samantha left Georgia and established herself as a successful attorney in New York City. Charlotte remained in Pikeville and continued working in the legal profession alongside their father.
Although the sisters share the same childhood memories, they have very different relationships with their hometown and family history.
Years after the original tragedy, another violent incident takes place in Pikeville. A school shooting results in the deaths of a principal and a young student, creating a new crisis for the community.
Charlie becomes involved in the situation, while Rusty asks Sam to return home. The sisters must confront their personal differences as the investigation develops.
The story moves between the past and present. This structure allows viewers to understand the events that shaped the Quinn family and the reasons their relationships became so complicated.

Each character has a connection to the Quinn family’s history, the local community, or the investigation that drives the series.
Rose Byrne as Samantha Quinn: The Sister Who Left Georgia
Rose Byrne takes the lead as Samantha Quinn, the older of the two sisters.
Sam is an accomplished attorney who has built her professional life in New York City. Her career focuses on patent law, giving her a lifestyle that contrasts with the small-town environment she left behind.
Her departure from Pikeville was not simply a career decision. The family’s traumatic experience during her teenage years played a significant role in shaping her future.
Sam attempts to maintain distance from the painful memories associated with her childhood. However, leaving her hometown does not mean she has escaped the emotional consequences of what happened.
When another violent event affects Pikeville, her father contacts her. His request creates a difficult decision because returning means facing people and places connected to her past.
Her relationship with Charlie is particularly complicated. Although the sisters experienced the same family tragedy, their responses were different.
Sam’s character represents someone who attempted to rebuild her life by creating distance from the past. Her return challenges the emotional boundaries she established over the years.
Rose Byrne’s Acting Career
Rose Byrne has developed an extensive career in both comedy and drama.
American audiences may recognize her from the comedy film Bridesmaids, where she appeared alongside Kristen Wiig and Maya Rudolph.
She also starred in Neighbors and its sequel, Neighbors 2: Sorority Rising. Other film credits include Spy, Insidious, X-Men: First Class, and Instant Family.
On television, Byrne received attention for playing Sheila Rubin in Apple’s Physical. She also appeared in the comedy series Platonic.
Her dramatic experience makes her a strong choice for a character dealing with emotional conflict, family tension, and unresolved childhood trauma.
In The Good Daughter, her performance must communicate Sam’s professional confidence while revealing the vulnerability beneath her carefully constructed adult life.
Meghann Fahy as Charlotte Quinn: The Sister Who Stayed
Meghann Fahy plays Charlotte Quinn, known to family and friends as Charlie.
Charlie is Sam’s younger sister. Unlike her sibling, she remains in Pikeville and develops her career in the same community where the family experienced its tragedy.
She works as a defense attorney alongside Rusty. Her profession places her in regular contact with the town’s legal system and people facing serious criminal accusations.
Charlie’s decision to remain in Georgia creates a different relationship with the family’s history. She cannot simply distance herself from the community where everything happened.
Her personal life also adds another layer to the character. Charlie has an estranged marriage to Ben Bernard, an assistant district attorney.
When the school shooting occurs, Charlie becomes closely involved in the events that follow. Her professional responsibilities and personal history make the situation especially complicated.
Meghann Fahy’s Rise in Television
Fahy has become increasingly recognizable through her television performances.
She first attracted a broad audience through The Bold Type, where she played Sutton Brady. The series followed three young women navigating their careers and personal relationships in New York City.
Her appearance in the second season of HBO’s The White Lotus brought additional attention. Fahy portrayed Daphne Sullivan, a character whose apparently comfortable lifestyle concealed complicated personal dynamics.
She later appeared in Netflix’s The Perfect Couple and the television series Sirens. Her film work includes the thriller Drop.
These projects demonstrate her experience portraying characters with complicated personal lives.
Charlie requires a different approach from some of Fahy’s earlier roles. She is a legal professional dealing with a community crisis while carrying the emotional weight of a difficult family history.
Her relationship with Byrne’s Sam is one of the production’s most important elements.
Brendan Gleeson as Rusty Quinn: A Father Caught Between Family and Justice
Brendan Gleeson portrays Rusty Quinn, the father of Sam and Charlie.
Rusty works as a defense attorney in Pikeville. His professional decisions have made him a controversial figure because he represents people accused of serious offenses.
His willingness to defend unpopular clients creates tension within the community. However, his work also establishes him as an important figure in the local legal system.
His relationship with his daughters is central to the drama.
Rusty wants the sisters to reconnect, but the family’s history makes that difficult. When the new incident occurs, he contacts Sam and asks her to return to Georgia.
His character connects the family storyline with the legal and investigative elements of the series.
Brendan Gleeson’s Major Film and Television Credits

His experience with complicated dramatic roles makes Rusty an important presence in the ensemble.
The character requires an actor capable of presenting both a demanding professional personality and the emotional responsibilities of a father.
Olivia Williams as Harriet ‘Gamma’ Quinn
Olivia Williams portrays Harriet Quinn, who is affectionately called Gamma.
Harriet is the mother of Sam and Charlie. Her place in the family’s history helps establish the emotional background of the story.
The Quinn sisters’ childhood experiences continue to influence their adult decisions. Harriet’s character is connected to that family history and the events that changed their lives.
Williams has built an impressive career across film and television.
Her film credits include Rushmore, The Sixth Sense, An Education, and The Father.
Television audiences may also recognize her from The Crown, where she portrayed Camilla Parker Bowles, and Dune: Prophecy.
Her appearance in the series brings additional dramatic experience to the central family storyline.
Michael Dorman as Ben Bernard
Michael Dorman appears as Ben Bernard, Charlie’s estranged husband.
Ben works as an assistant district attorney in Pikeville. His professional position places him on a different side of the legal system from Charlie and Rusty, who work as defense attorneys.
This difference creates an interesting professional connection between the characters.
His relationship with Charlie also adds personal complications to the story. Their marriage is no longer functioning as a conventional partnership, but their lives remain connected.
The new investigation brings additional pressure to an already complicated situation.
Michael Dorman’s Previous Roles
Dorman has appeared in several notable television productions.
He is particularly recognized for playing Gordo Stevens in Apple’s science-fiction drama For All Mankind.

Benardo’s role adds another perspective to the community and legal environment surrounding the sisters.
Audrey Grace Marshall as Young Sam Quinn
The series does not rely exclusively on adult performances to tell its story.
Audrey Grace Marshall plays the younger version of Samantha Quinn.
Her role is important because the childhood timeline explains how Sam developed the emotional distance that defines much of her adult life.
The younger Sam storyline also provides context for her relationship with Charlie.
Marshall’s performance helps connect the family’s original tragedy with the present-day investigation.
Drew Cheek as Young Charlie Quinn
Drew Cheek portrays young Charlotte Quinn.
The character appears in the earlier timeline, allowing viewers to understand Charlie’s childhood and her relationship with her older sister.
The younger version of Charlie is particularly relevant because the adult character chooses to remain in Pikeville.
The childhood storyline provides background for understanding why she develops a different relationship with the town from Sam.
Together, Marshall and Cheek help create continuity between the two timelines.
Why the Two Quinn Sisters Are the Center of the Series
Although the production includes several recognizable actors, the relationship between Sam and Charlie remains its central emotional focus.
Both sisters experienced the same family tragedy. However, their lives developed in different directions.
Sam moved away and built a career in New York. Charlie remained in Georgia and continued working with their father.
Their different choices created distance between them.
The new school incident brings the sisters back into contact under difficult circumstances. Their reunion is not simply a family gathering. It requires them to confront unresolved disagreements and memories.
Byrne and Fahy must portray the complicated combination of affection, resentment, and shared history that defines their relationship.
The younger actors also contribute to this central storyline by showing how the sisters interacted before their lives changed.
How the Supporting Characters Connect to the Main Mystery
The supporting performers have important functions beyond filling out the cast.
Rusty represents the connection between the sisters and their family history. Ben introduces another legal perspective through his position as an assistant district attorney.
Huck and Judith connect the story to the school and its surrounding community.
Kelly adds another element to the legal circumstances surrounding the investigation, while Lenore contributes to the wider character network.
These relationships make Pikeville feel like a community where personal history and professional responsibilities overlap.
The result is a story in which the mystery affects more than one household.
