It follows Monk, a brilliant detective with obsessive-compulsive disorder. He returns to solve one last case involving his stepdaughter Molly, a journalist preparing for her wedding.

He’s ingenious, he’s phobic, and he’s obsessive-compulsive. Adrian Monk’s offbeat antics have made him unfit for duty but he’s back as a San Francisco police consultant to help out on their most baffling cases. The brilliant but neurotic Monk is now fighting crime as well as his abnormal fears of germs, heights, crowds and virtually everything else known to man.
