After nearly getting caught by the dreaded "Bat Guards" for placing political posters, Hawar meets the lovely Hiro, a young girl who offers him shelter and helps him hide from the brutal secret police. In Hiro, Hawar finds a kindred spirit that like himself yearns for freedom and self-expression under a suppressive regime. Hiro's brother Shooresh supports Hawaar's underground activities and is sympathetic to Hawaar's feelings for his sister. But Hiro's cousin Houmayoun is also courting Hiro.
