At the very top, in the old villa at Krampusberg number seven, lives Krissi Krampus with her parents. Krampus Mama and Krampus Papa are professional Krampuses. In the summer, they have plenty of time. Together with Krissi, they lazily lie in the garden of their villa, drinking Krampus lemonade and nibbling on leftover chocolate Santas. Krissi tickles the mountain spirits out of their caves and comes up with pranks for the other winter frighteners in the neighborhood. One day, she discovers a new passion: painting! The Krampus parents are not at all pleased when Krissi's creativity spreads to the walls of the basement. So, Krissi looks for other places—and in the process, she finds a new friend: Together with Trixi Devil, she participates in a painting competition for humans. When the award ceremony approaches, the question arises whether the Krampus parents can overcome their prejudices against humans.
