A clique of girls in an English school wear a small yellow teddy bear on their uniform to signify that they have lost their virginity. Linda, the girls' leader, fears she may be pregnant from her window cleaner boyfriend, "Kinky", an aspiring pop singer. Desperate, and unable to confide in her parents, she must wrestle with her conscience and decide what course of action to take. Meanwhile, a concerned teacher learns the significance of the yellow teddy bears, and in trying to help the girls in question, puts her own career in jeopardy.
