Hard-working GP Tom Lattimer, in the midst of a divorce, is not exactly pleased when his father announces his own divorce and moves in.

When Tom's mother comes round for drinks and imbibes too much, Tom offers her Toby's bed for the evening, which sets up a most embarrassing situation.

Working hard to reunite his parents, Tom is appalled when Toby brings his attractive young receptionist Madeline home after an evening out at Covent Garden.

Toby has bought a new Rolls-Royce, which he lends Tom when Tom's mini is stolen. But the Latimer men are about to be without transportation: the Rolls is stolen as well.

When Toby stays out all night long, Tom surmises that he as spent the night with a woman—when in fact Toby had been in hospital, working with a colleague who suffered a heart attack.

Tom's plans for his parents' reconciliation seem on course when Toby invites Angela away for a romantic weekend—but Angela storms home when she learns who sponsored the weekend.
