Big-screen prequel to the popular 70s television series. Middle-aged ex-prostitute, former drug addict and all-around lowlife Jerri Blank (Amy Sedaris) emerges from prison at the age of 46 ready to start her life over again. Jerri arrives at her parents' home to discover that her father Guy (Dan Hedaya) divorced Jerri's mom and remarried before slipping into a coma. Jerri's stepmom Sara (Deborah Rush) decides to let her stay with the family in the hope her presence might bring Guy around, though she doesn't seem very fond of her new 'daughter'. Jerri decides to complete the education she abandoned years ago by enrolling at Flatpoint High School, where Principal Blackman (Greg Hollimon) has bigger fish to fry than a middle-aged sex offender as a student.
