Two sisters go into the family business they didn't know they had: catching killers. Attorney Rhonda Bird returns home after a long estrangement when she learns her father has died. There she makes two important discoveries: her father stopped being an accountant and had opened up a private detective agency, and she has a teenage half sister named Baby. Baby brings in a client to the detective agency, a young man who claims he was abducted. During the course of the investigation, Rhonda and Baby become entangled in a dangerous case involving a group of overprivileged young adults who break laws for fun, along with their psychopath ringleader and an ex-assassin victim who decides to hunt them down for revenge.
