Two years after her adoptive mother dies from an illness, 12-year-old Ella lives alone with her adoptive father Nolan. The two have formed a close father-daughter bond since her adoption at age 9 when her biological mother was killed by an abusive boyfriend. In Ella's eyes, her father is perfect and she is willing to do whatever it takes to sabotage those who get between them. Things grow complicated when Nolan begins to date a woman named Cecily who has a 14-year-old son, Zander.
