Maria (Sally Yeh) is a loyal member to the Hero Gang and its leader (Ben Lam) and did not hesitate to kill the mechanical maintenance staff who tried to escape.

Reporter Chong Chi Keung (Tony Leung) was fired because he was unable to photograph Pioneer I during the bank robbery.

Curly (John Shum), who works at the Research Department of the police force, invents a cannon that may be able to fight robots, which attracts jealousy from his superior.

Reporter Chong also tracks them to the shipyard and performs a comedy skit with Pioneer II, who is gradually developing more human reactions.

Chong then informs the police and Curly and Whiskey were arrested while Pioneer II fell into the hands of the Hero Gang again to be reprogrammed.

Pioneer II fights the gang, Curly and Whiskey installs cannons around the base and Chong goes to save the soon-to-be executed Master.

In the end, Curly, Whiskey and the now anthropomorphic Pioneer II lead a happy lives together while Chong dashingly abandons the pictures he took.
