"Sherrybaby" centers on 22-year-old Sherry Swanson (Gyllenhaal), who has just finished three years of jail time for robbery to feed her heroin addiction. She has a vision of landing a decent job and reconnecting with her daughter Alexis (Ryan Simpkins), who's been living with Sherry's brother Bobby (Brad Henke) and his wife Lynn (Bridget Barkan). Unfortunately, Sherry discovers that finding employment, staying clean and mastering motherhood are much harder and complex than life behind bars.

Awards also went to Daniel Sanchez Arevalo for his directorial debut "Darkbluealmostblack," Beatrix Christian for her "Jindabyne" screenplay, Anthony Dod Mantle for the cinematography in "The Last King of Scotland," and an audience award for Jonathan Dayton and Valerie Faris' "Little Miss Sunshine."
