Lurcio is given the night off when everyone goes out. Ammonia, Ludicrus and Erotica each give him money so that he'll be out of the house for the evening. Lurcio, however, has other ideas. He's expecting a visit from new neighbour, Lusha. He uses the money to buy a love potion and looks forward to a night of pleasure. Everything goes according to plan ... until the various members of the family sneak back home, expecting the house to be empty.
