Liars All is a 2013 American psychological thriller film. It was directed and written by Brian Brightly, and stars Matt Lanter, Sara Paxton, Gillian Zinser, and Torrance Coombs.

This psychological thriller finds a college group of friends playing Truth or Dare on New Year's Eve in London. A pop singer, Casey, (Stephanie McIntosh) is dating Dennis, (Torrance Coombs) a ladies' man and soccer star. Dennis' former girlfriend, Missy, (Gillian Zinser) is a psycho stalker. Mike (Matt Lanter) loves Missy but she only sees him as a friend. During the game we learn background about the players, like Mike and Katie (Sara Paxton) were first loves.

With booze, drugs, sex, video cameras, guns and untold relationships, the game gets out of control and Missy gets killed. At the police station, everyone tells their own different version of what happened. Was the killing an accident, suicide, or murder? The "who done it" has a surprise ending.
