Sucker Punch (2011)

Locked away, a young woman named Babydoll (Emily Browning) retreats to a fantasy world where she is free to go wherever her mind takes her. Determined to fight for real freedom, she finds four women -- Rocket, Blondie, Amber and Sweet Pea -- to join together to escape the terrible fate that awaits them. With a virtual arsenal at their disposal, the allies battle everything from samurais to serpents, while trying to decide what price they will pay for survival.
