The film functions primarily as a single comedic premise, though the performers' contributions manage to maintain a decent pace and prevent it from becoming entirely uncomfortable. Stanley Baxter portrays "Murdoch Troon," whose encounter with the affluent "Chingford" (James Robertson Justice) leads to his introduction to Chingford’s daughter, “Claire” (Julie Christie). Claire decides she wants to trade Murdoch's bicycle for a flashy red sports car, courtesy of his questionable acquaintance "Freddie Fox" (Terry-Thomas). He agrees to the exchange, motivated by his interest in her, but encounters some difficulties. Primarily, he lacks any driving experience and Claire’s father views him as something of a fool. The movie is fundamentally a loosely constructed comedy with plot points that don't quite add up. Despite this, it relies heavily on its male characters – Christie has limited screen time and minimal dialogue when she appears – who deliver some amusing and easygoing moments suggesting they were enjoying themselves during filming. Ken Annakin also brought in Kathleen Harrison, contributing to the lightheartedness, and there’s a bit of playful interaction involving golfers as well. It's not something you'll remember easily, but it provides an agreeable viewing experience.
