In order to save a life, she'll have to risk her own. Jennifer Lopez (Shall we dance, Monster-In- Law) takes a terrifying journey into the mind of a killer in this chilling, critically acclaimed psychological thriller. When a serial killer Vincent D'Onofrio (The Thirteenth Floor, Men In Black) falls into a coma before his last victim can be found, a child therapist (Lopez) must use an experimental treatment to enter his mind and learn his secrets before it is too late. The visually haunting world threatens her very existence when she becomes trapped by the terror inside. Now, an FBI agent Vince Vaughn (Wedding Crashers, Swingers) must rescue her from the killer's nightmare mind before he too is lost to the twisted world forever.
