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.

Based on a true story, The Heroes follows one of the most extraordinary and heroic exploits of World War II. After months of rigorous training in the north of Australia, a team of 14 men, most barely out of their teens, set sail from Cairns on board a leaky old fishing boat called 'The Krait'. Their mission, code-named Operation Jaywick, became a tense voyage through thousands of kilometres of Japanese held territory to launch a daring attack on Singapore Harbour. The raid is a success but within sight of safety they encounter a Japanese destroyer, and all prepare to die rather than be taken prisoner.
