Sezon 1

Greg, Vicky, and Justine arrive in town and are looking for an apartment near college. Each of them wants to rent the 5A for themselves alone, but the rent is too expensive: they have no choice but to become roommates. On the first night, Justine discovers, behind the wallpaper in her room, a hidden door. The roommates uncover this door, which opens onto a closet lined with copper, in the middle of which lies a mysterious trunk containing the skeleton of a young man. By opening the trunk, they accidentally release the ghost of Théophile Langevin, who has been trapped there since 1957 in a ghostly coma.
