The merriest Mr. and Mrs. team ever, William Powell and Myrna Loy, are at it again, for better...and worse! The domestic duo that enchanted filmgoers in The Thin Man series are completely out of their minds in this hilarious misadventure. On the night of her fourth wedding anniversary, Susan Ireland (Loy) discovers her hubby Steve (Powell) has been out carousing with an old flame. With the support of her overenthusiastic mother, she files for divorce, but the cunning Steve feigns insanity in order to postpone the proceedings and convince her she's got it all wrong. The plan almost works, but the trickery is turned when Susan has him committed to an asylum. It's nonstop fun as Steve tries to escape and win back her love -- and he literally has to go nuts to do it!
