Anita and Clive Debanks have been married for 28 years and have led an uneventful life. But all that is about to change. Although in a loveless marriage, Clive has never been unfaithful. However, as preparations for his fiftieth birthday are underway, Clive feels that life is passing him by and has a yearning for one last fling. To this end, he chooses three prospective partners from the ‘lonely Hearts’ column in the local paper. By a strange twist of fate, the same paper is offering a Caribbean cruise, as the first prize, in a competition to find the perfect married couple. Anita enters the competition but keeps it a secret from Clive. A photographer arrives to take pictures of the happy couple the night Anita is away, and Clive is busy at home, entertaining one of his new dates. From that point onwards, things get a little complicated, to say the least. The action is fast and furious in this hilarious farce.
