An astronaut and crew land on Jupiter's 13th moon and find a monster and women from Atlantis.

Tse Mei-chen is deeply concerned about her only family, sister Bo-chen who is obsessed with perfecting her detective sensibilities. One day, Bo-chen returns home in panic to relay to her sister and her boyfriend detective Ma Tin-lung the horrifying murder of Siu-ying by her husband Tsui Kai. But a subsequent visit to the couple's, the cousin of Bo-chen's best friend Wong Kam-fung, proves the alleged crime false. Incognizant to all, the victim was Siu-ying's twin sister Kwok-ying, who bore witness to Tsui's misappropriation of their wealth for drug trafficking. Refusing to abandon the probe, Bo-chen is held up by Tsui. Deeply perturbed by Ma's investigation into his secret dealings, Tsui coerces Mei-chen to distract her boyfriend long enough for his escape. Refusing to bow to the threat, Mei-chen informs Ma who leads his squad to the rescue of the sister and arrests Tsui and his accomplices.

Produced by the Eastman Kodak Company and shot in a then-experimental process, two-color Kodachrome, Martha Graham's dance "The Flute of Krishna" is performed by students from the Eastman School of Music. It's likely (but unconfirmed) that the film was directed by an uncredited Rouben Mamoulian.

The plot of the film is taken from the legend of the Azerbaijan Maiden Tower. According to legend shirvanshah fell in love with his daughter and wanted to marry her. Learning of this daughter Shirvanshah jumped from the top of the tower in the Caspian Sea.
