Fisherman Jack discovers an abandoned building emerging from the ocean while returning to shore, sparking his curiosity to explore further.
Upon entering the building, Jack finds it filled with historical artifacts, including old cannons, suggesting it was once a fort used for coastal defense.
Jack encounters a locked door and creates an escape route by removing loose bricks from the wall, leading him to a central room with a mix of ancient and modern items.
After discovering unexpected objects, Jack decides to call the authorities, feeling a moral obligation to report his findings, despite his initial excitement.
French police launch a search operation based on Jack’s call, ultimately locating him on the open sea, where he surrenders to their custody.
Jack learns that the fort is a historical site and a location for entertainment shows, where he unknowingly shared space with tigers used as props, adding a dramatic twist to his adventure.
