Mortina and her best friend, Sadness, an albino levretta dog, live with their Aunt Domovina and spend their days playing with ghosts in the Abandoned Villa. But one day Mortina gets into trouble. Out of the blue, the children from the village, Mortina's friends, come to the villa because they have received mysterious invitations. And this was just when Aunt Domovina disappeared. And then there was the terribly cranky cousin Dilbert, who came to visit them.
