In a sunny, happy, optimistic and often absurd 1954, Timothy and Jane graduate from University. Under pressure from their parents they have to find a job and a husband, respectively. Timothy's family send him off to meet a series of influential and increasingly eccentric uncles, while Jane's mother lines up a series of eligible but dull potential husbands. A chance meeting with a tramp brings the couple together as his street piano - named Minnie - gives everyone an irresistible and unstoppable urge to dance. The tramp gives Timothy the job of looking after the piano for a month. Once the month is over and after all kinds of wonderful adventures - including a ride in a flying saucer - Minnie the piano is passed on to a new couple and Timothy and Jane's families are reconciled.
