Louise Henderson, the editor of a top British fashion magazine, is also an international jewel thief; assisted by photographer Raymond Lowe and model Claudia, Louise uses her position, requiring frequent trips abroad, as a front for her illegal activities. When the police suspect that she is planning to steal an ancient Arabian medallion from Morocco, secret agent Simon Grant infiltrates her operation, posing as a safecracker, and coerces Louise into accepting him as a partner. The plan is for Claudia to enter Morocco wearing an imitation medallion and leave wearing the real one. Once in Morocco, Simon is instructed to cooperate with Police Chief Barrada and his assistant, Michele Craig. While the group is taking pictures for the magazine in the deserted ruins of a Berber fortress, Lowe learns Simon's true identity, and Simon is forced to kill him. After Simon has found the medallion in a grave site near the desolate fortress, Claudia takes it from him, but she is shot by Michele. By the time the police arrive, Louise, Simon, and Inspector Barrada have all been outwitted by Michele, who has disappeared with the medallion and is presumably on her way to Tahiti.
