Luke runs a sanitarium for the idle rich.  The nurses are so pretty that the patrons actually enjoy being sick.  A certain rich man, hearing of this, throws a fit to get in; his wife does take him in.  He slips Luke a hundred dollar bill to tell his wife that he is, indeed, sick.  When assured that there are only male attendants, she leaves.  She returns later, to deliver a care package for her hubby, but forgets her handbag when leaving.

When she goes back for it suddenly, she surprises the staff of lovely female nurses.  She decides to get even, by returning as a man; a riot ensues and most everyone in the place ends up in the swimming pool, with Luke at the bottom.
