"Short Term 12" is told through the eyes of Grace (Brie Larson, "Scott Pilgrim vs. the World", "21 Jump Street"), a twenty-something supervisor at a group home for troubled teens. She's passionate, tough and in love with her long-term boyfriend and co-worker, Mason (John Gallagher Jr., "The Newsroom"). But Grace's difficult past, her fierce independence - and the arrival of a distraught new girl at the facility - create complications that push Grace and Mason to the brink. How this couple overcomes those challenges is what makes this film an entirely unique love story. Grace and Mason come to embrace a surprising future together, discovering truth, humor and family in unexpected places along the way.
