In the 22nd century, scientists from an energy-depleted Earth research new fuel sources in the far corners of the solar system, where they discover an ancient alien race from Jupiter as well as the emergence of an apocalyptically dangerous black hole. Koji Hashimoto's 1983 sci-fi adventure was conceived as a Japanese competitor to the upcoming sequel to Stanley Kubrick's classic 2001, titled 2010, and often mirrors the sequel's plot.

Billy Wong is a New York City cop whose partner is gunned down during a robbery. Billy and his new partner, Danny Garoni, are working security at a fashion show when a wealthy man's daughter, Laura Shapiro, is kidnapped. The Federal authorities suspect that Laura's father is involved with Mr. Ko, a Hong Kong drug kingpin, so the NYC police commissioner sends the two cops to Hong Kong to investigate.
