Marge, Declan and Pascal receive a new order - to deliver a mysterious cargo - three boxes - to a mysterious mansion. Everything would be fine, but the map that they receive along with the parcels and which should lead them to their destination is made of something resembling leather. But there are no animals with such skin... What awaits them in the estate on a hill, surrounded by a cemetery and drowned in fog? Will they receive the due payment or will they themselves pay for knocking on the ghostly door of this strange place? Is it even possible to return from the Haunted Mansion?
