SECOND LIVES is about people's identities, both real and created, and how the two become confused and conflated, particularly through the use of the Internet and an obsessive participation in role-playing games. The story follows three geeky guys who were former college classmates, whose respective make-believe personas lead to their "real" lives colliding ten years later. Added to the mix is the girlfriend of one of these three men, who unlike the men appears to be grounded in reality. However, it's never totally clear until the very end who is play-acting and when. Even the characters themselves aren't always sure - -especially when the outcome is murder.
