Plot Summary of The Good Daughter with Spoilers and the Ending Explained

In 1989, thirteen year-old Charlie Quinn and her fifteen year-old sister, Samantha had to move after their home was firebombed. The girls’ father, Rusty Quinn, is a lawyer in Pikeville, Georgia who represents controversial defendants. Rusty’s most recent client allegedly kidnapped and sexually assaulted a teen girl who later took her own life.
After Rusty’s client is freed, two masked men show up at the Quinn’s temporary home. One of them shoots and kills the girls’ mother, Gamma. The men, one of whom Sam recognizes as Zach Culpepper, a former client of their father’s, says they have come for a stash of cash that Rusty was rumored to keep in the house.
The men force the two girls out into the woods. Zach tells his accomplice to slit the girls’ throats. Samantha urges Charlie to run, and she does. Sam is shot and buried alive by Zach’s accomplice, but is able to dig herself out.
