Accompanied by their respective spouses, Cohen and Kelly go to Scotland to buy plaids, each having received a tip that the Prince of Morania, a style dictator, is to have a plaid motif in his spring collection. Cohen buys all the plaids of McPherson, while Kelly purchases those of McDonald. Cohen gets into trouble with a stranger on the golf course and is horrified to find that he has insulted the prince; they attend the races where the prince is expected to show himself in plaids, but his clothes are covered by his raincoat. Thinking themselves ruined, each decides to commit suicide; however, when Cohen tries to drown himself, Kelly rescues him. They astound McPherson and McDonald by asking them to buy back the plaids, but when the prince is seen wearing them in a parade, the Scotsmen gladly pay them a fortune.
