Seth Winnick has it all--a successful career in television, good friends, and a passionate relationship with the beautiful Chelsea Turner. However, when he fails to make a timely marriage proposal, Chelsea behaves as is she has been bitten by a rapid squirrel. The two redirect their passion into malice and forge a sordid "anti-relationship," replacing love and tenderness with vengeance and venom, which fuels a series of bids to out do the other with acts of cruelty. This unromantic comedy features cameos by Jason Bateman, Christian Slater, and Tiffani-Amber Thiessen.
