Movie Review: Deadgirl (2008)
Synopsis: Teenagers Rickie and JT cut class and explore an abandoned insane asylum. While escaping a guard dog, they entered a locked room and discover a naked woman tied to a table. Rather than freeing the woman, who they later learn cannot be killed, JT, instead, decides to keep her tied up so he and his friends can continually rape her, something Rickie is opposed to but is too weak to prevent.
