Adrian Monk is on a roll, solving murders as fast as they come and not obsessively counting his cereal until it's in the bowl. But when his therapist, Dr Kroger, leaves for Germany, Monk can't tie his shoes, forgets how to swallow and loses track of his blinking. Desperate, he follows Dr Kroger to Germany where he sees a man with six fingers - the man responsible for his wife's death. Monk has to battle with his phobias and the unfriendly Polizei to find his man.
