A terrifyingly funny and frighteningly animated story about a family of grim, though clumsy monsters.

Fay SIelska is an ordinary, somewhat rebellious teenager. Her younger brother Max, due to his superior intelligence, is on a broom with schoolboys. Parents are so busy that they hardly find time for family life.

One day Fay takes all the Siels to the dressing room. She dresses up for a mummy, her brother for a werewolf, a mom for a vampire, and a dad for Frankenstein. The play is front until it turns out that, as a result of the curse of their disguise, they ceased to be just a joke, and became a reality. Yes Yes! Wishbones have been transformed into monsters!

From this point on, they are doing everything they can to get rid of the curse and avoid getting caught by the despotic Count Dracula. Soon it turns out that being a monster has its good side. Max can himself chase schoolboys, his daddy is stronger than all Avengers, mommy mesmerizes even sellers in the store, and Fay is just immortal!
