This drama tells the extraordinary story of Jack (Jacob Tremblay in an incredible debut), a spirited 5 year-old who is looked after by his loving and devoted Ma (Brie Larson). Like any good mother, Ma dedicates herself to keeping Jack happy and safe, nurturing him with warmth and love and doing typical things like playing games and telling stories. However, they are trapped in a windowless, 10-by-10-foot space, which Ma has euphemistically named “Room.” As Jack’s curiosity about their situation grows, and Ma’s resilience reaches its breaking point, they enact a risky plan to escape, ultimately bringing them face-to-face with what may turn out to be the scariest thing yet: the real world.
