Plot
Gruesome School Trip follows Onnoval, an awkward 11-year-old who feels uncomfortable around his classmates. He believes that if he loses control, by becoming too excited or getting into a fight, he will turn into a werewolf. Onnoval keeps his worry a secret, even from his school sweetheart, Liselore.

After a particularly humiliating incident at school where the bully Gino grabs his love poem to Lislore and tears it to pieces, Onnoval writes a horror story where he takes revenge on his classmates.

The story is a way for Onnoval to cope with his humiliation at school. However, fantasy soon turns to frightening reality when Ferluci takes possession of Onnoval's story and makes a deal with the devil to make it come true.

If Onnoval does not rewrite the story immediately, the planned school trip to the Horror Park will end in disaster. But in order to rewrite it, he must first get his story back from Ferluci.
