Roberto Balagtas is falsely arrested for treason and sent to prison where he is tortured. He escapes with other prisoners, but only Batagtas survives the escape, carrying with him a treasure map left by one of the others. He crosses paths with Ming Tang (Strong) and a group of Chinese smugglers, with whom he finds the treasure. The booty makes him extremely wealthy, and he changes his name to Don Diego Sebastian. He then goes back to the Philippines to seek his revenge.
