The peace and tranquillity of an idyllic, suburban city is suddenly broken. Behind a picket fence and manicured lawn, teenager Sara awakens, startles as a rush of cold air gently pushes her bedroom door open. Across the hall her parents' door lies ajar and as her eyes adjust to the darkness she finds her parents gagged and tied to the bed. Knocked unconscious she is later awoken by a deranged killer and given 60 seconds to decide who dies, her mother or father?
