The Bad Seed Returns stars Mckenna Grace as 15-year-old Emma, a seemingly typical teenaged girl who is anything but that. Set several years after the murderous events of the first movie which left her father (Rob Lowe) dead, Emma is now living with her aunt Angela and navigating high school. Angela's husband begins to suspect that Emma may not be as innocent as she appears and suggests sending her off to boarding school. Meanwhile, a new girl (Ella Dixon) at school seems to know Emma's secrets, leaving Emma no choice but to slip back to her old ways and take care of her enemies by any means necessary.
