Wrong Turn 4: Bloody Beginnings is a 2011 American horror film written and directed by Declan O'Brien and the fourth installment in the Wrong Turn film series. The film serves as a prequel to the previous three films. In 1974, at the Glensville Sanatorium, West Virginia, Dr. Brendan Ryan (Arne MacPherson) shows local psychiatrist Dr. Ann McQuaid (Kristen Harris) around the psychiatric hospital. He shows his three deformed patients, Three-Finger, One-Eye and Saw-Tooth, who all have the ability to sustain injury and not feel it. While Dr. Ryan and Dr. McQuaid move on, one of the mental patients grabs Dr. McQuaid's hair and rips out her hair clip, which she does not notice. The patient gives the hair clip to Saw-Tooth. The three deformed patients use the clip to pick the lock and escape their cells. They release the other patients and together they kill the orderlies and the doctors including McQuaid and Ryan. In the present day, nine Weston University students: Kenia (Jennifer Pudavick), Jenna (Terra Vnesa), Vincent (Sean Skene), Bridget (Kaitlyn Wong), Sara (Tenika Davis), Claire (Samantha Kendrick), Kyle (Victor Zinck, Jr.). Daniel (Dean Armstrong) and Lauren (Ali Tataryn) are snowmobiling, on their way to their friend Porter's cabin in the mountains.
