S1, E1: As Alison and Nabil are desperately searching for an apartment to move in together, the couple is pleasantly surprised to learn that they have inherited a (very dilapidated) castle. Despite the notary's advice, they decide to move in and turn the place into a hotel. They are unaware that they are not the only inhabitants: the castle is haunted by a group of ghosts who had been living a peaceful existence and are not happy about the couple's arrival. When they learn about the hotel project, they decide to put a plan in motion to drive Alison and Nabil away — they will try to haunt them.
