Identity (2003)

When a vicious storm breaks out in the Nevada desert, 10 people seek refuge in an isolated motel. At the same time, a serial killer (Pruitt Taylor Vince) under the care of psychiatrist Doctor Mallick (Alfred Molina) -- who has just found the killer's revealing journal -- awaits execution for murdering a group of motel guests. When the storm-stranded travelers realize they are being killed off one by one, limo driver Ed Dakota (John Cusack) bids to stay alive and reveal the murderer's identity.
