Rose Byrne and Meghann Fahy Anchor Peacock’s The Good Daughter

Meghann Fahy plays Charlie, a defense attorney who works with her father, Rusty, in the Georgia town where they grew up. Rose Byrne plays Charlie’s older sister Sam, a New York lawyer who has been estranged from her family for more than a decade. When a shooting at a local school leaves a teacher and a student dead, Sam returns home to represent the teenage suspect, Kelly Wilson.

The case revives memories of the sisters’ mother, Gamma, who was killed years earlier when two masked teenagers came to the family home looking for Rusty. The series revisits that night across its six episodes, gradually adding details. In the present, the sisters clash over how each responded to their mother’s death: Charlie stayed close to their father, while Sam left town and cut contact.

The show also follows Charlie’s strained personal life and the investigation into the shooting, as well as an attack on Rusty. Kelly’s learning impairment and vulnerability to bullying form part of the case Sam takes on. The series examines Sam’s experience living with a disability, including the physical limitations that shape her daily life and courtroom work.

Fahy and Byrne’s performances and the sisters’ tense, affectionate relationship give the drama much of its force. The story’s family dynamics can feel overworked, and revelations in Kelly’s case sometimes arrive in heavy bursts of explanation. Still, the central relationship remains compelling as the sisters confront old wounds alongside the case.
