Contradiction: Spot The Liar!

"Contradiction is an interactive crime drama that uses live-action video for the entire gameplay. It's a whole new take on the concept of an interactive movie and takes the genre to a whole new level of playability. Contradiction plays as smoothly as a 3D graphics game. You'll be able to move freely in the game environment, collect evidence and witness constantly changing events. However, the heart of the game is the interrogation of the people you meet, who you can question about all the evidence you've collected and things you've seen. It's about discovering contradictions in their answers, convicting them and moving the game forward."
