The intergalactic bounty hunter Jane Flower is followed home from a nightclub by a man who professes love for her and reveals he is Cobra, one of the most wanted criminals in the galaxy. Jane is one of three triplet sisters who are the princess heirs to the wandering planet Dakobar. She drags him on a mission to rescue her sister Catherine from a prison orbiting an ice planet where she is held by the evil Crystal Boy from the Space Mafia Guild, an android with a transparent skeleton. But Catherine has been corrupted by Crystal Boy and kills Jane. The only hope for Dakobar is if all three sisters fall in love with the same man or else the only surviving sister is good. The only alternative is now for Cobra to find the third sister Dominique, an ice guerilla on the Red Star planet.
