It's the start of the winter season and there's a new teacher in town at Villains Academy: the notorious dragon rider Felix Frostbite. Class Z is in awe of him and his lessons on venomous beasts and mythical creatures, but werewolf Bram is suspicious.

Soon Bram and his friends the Weirdoughs uncover Felix Frostbite's evil plan to steal all the dragons from the Wicked Woods and leave Villains Academy undefended. Have the gang learnt enough to outsmart their troublesome teacher, or will Felix Frostbite's heist go down in villain history?
