The film sees Kristen (played by Amber Heard), held a psychiatric hospital with little knowledge of how and why she got there.
Covered in bruises, cuts and also sedated with drugs, she struggles to unravel the mystery meeting 4 other similar young girls along the way. They are patients too, but know little more than Kirsten.
Something is certainly amiss on the ward where strange noises are heard at the dead of night, and everyone there seems to act suspiciously.
As the other girls gradually vanish Kirsten races against time to discover the truth about the ward and how she got there. Here very life depends on it!
