Undermind

A young lawyer becomes trapped in an eerie alternate reality in this haunting psychological thriller from first-time filmmaker Nevil Dwek. Derek (Sam Trammell) seems to have the perfect life. A 27-year-old lawyer with an impressive career and remarkable talent in the courtroom, he's on the fast track to success when he awakens in a strange apartment next to an unknown woman who inexplicably refers to him as "Zane." Though everything in this altered reality seems familiar, nothing seems right, and Derek soon discovers that he and Zane have somehow traded identities. Forced to see life from the other side of the spectrum, Derek and Zane must now reevaluate their entire lives to find out who they truly are on the inside, and what they aspire to become in a world where nothing is certain. ~ Jason Buchanan, All Movie Guide
