Two carefree young women, Jackie and Monica, are hitchhiking through the French countryside when they stumble upon an apparently deserted mansion. Intrigued by the allure of exploring the unknown, they decide to break into the house, seeking adventure and respite. As they wander through the lavish, yet eerily abandoned rooms, their curiosity leads them into intimate and playful encounters, completely unaware of the looming dangers that linger within the walls. Their frivolous exploration is abruptly interrupted when they discover that the house isn’t as empty as they first thought.

As their sense of security crumbles, the duo realizes they have unwittingly walked into a web of crime and intrigue. The mansion is a hideout for a group of jewel thieves, who return unexpectedly and catch the girls in the act of intruding. The thieves, now aware of the presence of Jackie and Monica, add them to their plans in a twisted game of cat-and-mouse. The tension escalates as the girls attempt to navigate through a maze of deception and peril, striving to outwit their captors and escape with their lives.
