After a series of natural catastrophes and global economic collapse, the world has become a lawless place. Anarchy rules the streets, and warlords take power by brute force. The ruined cities are filled with street children and orphans who are terrorized and robbed of their food and last possessions. One warlord is Bosco, a ruthless killer who is obsessed with perfecting his power through Martial Arts. Together with Cleo, Bosco‘s lascivious partner, he kills Master Thach, keeper of a sacred book of Martial Arts. Master Thach‘s last pupil is Jonas, an orphan whom Master Thach raised and taught all he knew. Jonas survived Cleo and Bosco‘s attack with the help of a friend, and now returns to the city to reclaim the lost book. Jonas is an excellent Martial Arts fighter, and he has a pure heart. In the city he meets Vincent „Vince“ Lakotta and Marie, Vincent‘s beautiful and smart sister, and their tough gang of street kids. Together, they begin a campaign to give back to the poor and end Bosco‘s rule. Unfortunatly, one of the gang members, Malte, is moved by jealousy of Jonas to betray the gang‘s hideout. Bosco‘s soldiers decimate the gang, recapture the book and take Vince prisoner. This is the bait to lure Jonas and Marie to Bosco‘s hideout. In the final showdown, our heroes overcome Bosco and Cleo and a new dawn appears in this dark time.
