The catacombs

Katelyn was an average woman. She goes to France, where she reunites with her childhood friend, Miranda. They spend minutes catching up and relishing in memories of the past. Katelyn wanting to do something with her old friend, remembers seeing a poster for the catacombs and they decide to go to take the tour. When Katelyn, Miranda, and her husband Mike arrive at the start of the tour, Katelyn meets a young woman, Krystin. But as the tour begins through the catacombs, the walls collapse, separating the four from the rest of the tour. Amidst their panic, the floor beneath them gives way sending them further underground. The fall renders Katelyn unconscious, and she awakens to her friends in a bigger panic than before. Will they make it out, or will they succumb to the terror that is, the catacombs.
