Marika, Scarlett, and Tony work as butlers and waiters for a very wealthy baroness; Marika is in charge of the staff and takes care of organizing charity events and parties that the baroness likes to throw from time to time. This time, the baroness will host a grand party to celebrate her birthday, and for the occasion, she will wear a diamond necklace, never shown in public, of priceless value, inherited and belonging to her family for centuries. However, to protect her precious necklace from potential theft, the baroness decides to entrust the valuable jewelry to her trusted staff manager Marika, who, unsuspectingly, will have to keep it in a vault hidden inside the staff quarters little ,a seemingly inconspicuous hiding place; meanwhile, in the baroness's huge villa, a fake copy of the necklace will be kept. Marika, being a cunning ex-thief, smells the opportunity and contacts Raimondo, a poor dumb lackey who she used to take with her before ending up in jail. This time, however, the opportunity is too tempting. So Marika gives Raimondo instructions on the plan to carry out, after all, only she knows where the real necklace will be hidden. At the end of the workday, after the necklace has been placed inside the dependent building's vault, and when Marika, Scarlett, and Tony meet up in the, Raimondo will have to take action. Tony will have to gag Marika and Scarlett with tape and a large sponge, then do the same to himself; the three, now adequately silenced, won’t be able to call for help. Tony will then tie up Scarlett with many ropes, and once she is immobilized, Marika will tie up Tony. The two unsuspecting waiters will be left tied up and gagged in the kitchen, while Marika will lead Raimondo to the vault to retrieve the very precious necklace. During the theft, Scarlett and Tony squirm furiously to try to raise the alarm, despite the immense efforts, when Raimondo and Marika return the two waiters are still bound and gagged. Marika foxy's plan is working perfectly, so as not to arouse suspicion Marika will be tied up by Raimondo in the company of Scarlett and Tony. Now Scarlett and Marica are tied to the chairs and very stuck, while Tony is hogtied at their feet, the three are left to moan furiously in the kitchen while Raimondo has plenty of time to escape with the baroness's necklace. While the three are squirming, Marika thinks about how brilliant she was to come up with such a plan, and enjoys watching her two colleagues as they squirm furiously, while she will only have to pretend, wait for dawn for someone to free them, and from tomorrow she will be a rich woman. But not all plans end as one designed them, and perhaps Marika is not as smart as she thinks she is.
