In the throes of his divorce, Jeff has to take care of his estranged wife's sheep-dog, Bubbles, but, due to Maplin's No Pets policy, has to hide the dog in his chalet. Hearing noises, people assume he is entertaining a young lady and Gladys is not pleased though all is revealed when a private eye, hired by Jeff's wife to catch him out with a member of the opposite sex, bursts into his room.

Persistent rain literally washes out the outdoor entertainments usually provided for the children and, to make matters worse, Partridge has hit another kid - who will be compensated by winning a singing contest. Unfortunately this has already been rigged to accommodate another winner so that Ted has to come up with a plan to keep everybody happy.

Peggy Ollerenshaw, the most vocal member of Miss Cathcart's cleaning staff, is anxious to be a Yellowcoat entertainer and Jeff arranges for her to have an interview. To give her an opportunity to prove her entertaining skills Ted invites her to impersonate a shark in a poolside routine which will involve bathing beauty Spike being rescued from the beast's jaws. Unfortunately she isn't very good and will need to wait awhile before she can bid farewell to her dusters.
