Undermind (2004)

This meditation on the concept of identity is the directoral debut of Nevil Dwek. Derrick (Sam Trammell) wakes up one morning to discover a woman next to him who he is unfamiliar with. Referring to him as "Zane," the strange woman seems to think that Derrick is a criminal, and when he steps out into the world, he is regarded that way by everyone else as well. Trapped in an alternate reality, Derrick is confused as to which way to turn. Meanwhile, the real Zane has awoken to find he is living Derrick's life, and is in a similar state of turmoil. Faced with the choice, the two must make a unique decision to determine exactly who they want to be.
