Have you ever wanted to be a doctor? Even for just a day? What could possibly - outrageously - go wrong?Stanley White is a tourist visiting an island community when he consults Doctor Black, the only local physician, for a prescription. White is a playwright who has always wanted to be a doctor. Black is an amateur playwright who needs to attend the dress rehearsal of his first play tomorrow (Saturday) being held off island. He persuades White to take over his practice for the day, overcoming White's obvious reticence with lots of reassurance and minimizing the risks. What follows is a parade of wacky patients seeking treatment from the hapless fake doctor who has problems of his own.

This is a hysterical romp and yes, there is a surprise ending.
