From the directors of There's Something About Mary.
Charlie Baileygates (Jim Carrey) is a 17-year veteran of the Rhode Island police force. He is mild-mannered, hard-working, always helpful and a devoted and loving father of three sons.
Unfortunately, Charlie has split personality disorder, and when he runs out of medication Charlie's hyper-aggressive alter ego Hank appears. Hank's got a filthy mouth, drinks like a fish, and enjoys a good fight. Charlie and Hank have nothing in common with the exception of Irene Waters (Renee Zellweger), a beautiful woman on the run, with whom they have both fallen in love. Now Hank and Charlie must wage war with each other for Irene's affections.
