Bradford teenagers Rita and Sue regularly baby-sit for successful uburbanites Bob and Michelle, whose comfortable lifestyle is in striking contrast to their own bleak existence. One evening, when Bob is taking them home, he suggests a detour to the moors. Impressed by his flashy car and worldly ways the girls are smooth-talked into a three-way sexual relationship that becomes very much part of their lives. At first, it's a bit of a laugh, but people are quick to point the finger and the affair is soon in the open.
A morally ambiguous, bawdy British comedy.
