Two young men growing up in Taitung like the same girl. In an act of jealous, they injure each other with fireworks when participating in the Bombing Master Han Dan festival. Unfortunately, this accidentally causes the girl to die as well.

An upstanding young man commits a reckless act that ends in life-changing tragedy. His doomed rival becomes his friend, only to become his rival again. Set against the tradition where men seek atonement by submitting themselves to ritualized firecracker attacks (as effigies of the deity Han Dan), this film not only reveals unique aspects of Taiwanese culture but its complex psyche as well. Featuring stunning cinematography and nuanced performances, Han Dan weaves universal themes into a novel, eye-opening moral tale.
