During his voluntary stay at an Irish mental hospital, manic-depressive Clayton falls head over heels for involuntary schizophrenic patient Anna. Clayton's doctor feels the relationship is helping him heal, but Anna's doctor thinks it is a disaster waiting to happen and tries to separate them.
If Clayton is to stay with the woman he is fallen in love with, he can pretend to be crazier than he really is to prolong his stay in the facility or he must escape with Anna.
