A rich financier organises a sensational robbery, using mercenaries who don’t know who is behind the hit. The police manage to track down one of the thieves, but can’t trace who masterminded the theft. So the insurance company sends a beautiful and unscrupulous bounty hunter to collaborate with the detective leading the investigation. Using her own fairly unconventional methods, the beautiful Greta (Greta Martini) approaches various people in the jet-set and after a few failed attempts, pinpoints Terry Caldwell as the probable mastermind. The two embark on a dangerous game of seduction, with the poorly hidden aim of getting the other in the sack. With her charm and bewitching ways, Greta manages to make a breach in Caldwell’s heart, making it easier for the police to find the evidence they need to trap him. Caldwell, driven by the desire to surprise her, plans a new hit and leaves Greta with the choice of whether to betray him or have him arrested. Will Greta succom to Caldwell’s charm, or will she be faithful to her duty?
