In the year 2043, an evil crime lord is trying to take over the world. Only one government official stands in his way, and plans to send him to prison, so The General and his minions Kent, Thai King, and Toyota travel to the year 1993 to kill the official before he has a chance to get into office. During a battle with The General's minions, the Future Cops Lung, Broom Man, Ti Man, and Ah-Sing hear of their evil plan and devise a plan of their own to travel back in time to protect the official.
