Breaking Down the Hard-Won Ending of ‘The Good Daughter’

This confrontation opens the finale of The Good Daughter, Peacock’s six-part limited series adapted by Karin Slaughter, who wrote every episode, from her 2017 novel. More than 20 years earlier, two masked men came into the Quinn kitchen in Pikeville, Georgia, looking for Rusty (Brendan Gleeson), a defense attorney who represented the people nobody else in town would. They found his wife, Gamma (Olivia Williams), and his daughters instead. They killed Gamma. Sam took a bullet to the head and was left for dead. Charlie, the younger sister, escaped after Zach Culpepper sexually assaulted her. Police arrested Zach, who went to prison, and they shot dead his brother, Daniel, whom they named as the second assailant. The Culpepper family has always insisted Daniel was innocent, and we learn in the finale that they were telling the truth.

In the years that followed, the sisters grew up and then apart, Sam to patent law in New York, Charlie to a public defender’s desk in the town where it happened, until a fight in New York left them estranged. What draws them back together is a shooting at the local school that kills the principal, Doug Pinkman, and a young student named Emma. Kelly Wilson (Shayna Benardo), an intellectually disabled teenager who tends to tell people what they want to hear, is found with the gun in her hand, and Rusty takes her case. Huck teaches at the school, and Charlie had recently spent a night with him. Rusty dies quietly one night in Episode 4, before he can see the case through. By the finale, Sam has taken up Kelly’s defense, and Charlie has at last told her sister what Zach did to her in the woods.
