Petit Spirou dispute un match de foot avec ses copains. Mais Vert' envoie la balle dans le soupirail d'une maison que l'on dit... hantée ! La trouille au ventre, les 3 amis vont tenter d'aller récupérer leur ballon, l'un en se mettant une armure, l'autre en se déguisant en monstre pour faire peur à la créature qui hurle abominablement depuis la cave...
Little Spirou is playing a soccer match with his friends. But Virgil kicks the ball through the basement window of a house which looks like it’s haunted! Scared stiff, Spirou, Virgil and Cassius go to try and get their ball back, one dressed in armour, and another disguised as a monster to scare the creature which is shrieking so horribly down in the basement… But maybe the monster is not so terrible and all the drama is a big fuss about nothing!
