Story without spoilers

The story begins around Halloween, when Professor Latouche and Miss Rateau take up residence in a supposedly haunted house. Its ghostly inhabitant is Anatole, described as the biggest dunce in the history of Saint-Potache School. Rather than remaining a distant legend, Anatole becomes an active source of mischief.

Ducobu, Léonie, their parents and Kitrish are pulled into the ghost’s series of unexpected adventures. The premise combines the familiar school setting with a Halloween mystery, leaving the characters to deal with the consequences of Anatole’s presence while the holiday adds an unpredictable edge to the events.

What to expect

This is a family comedy built around Halloween, school humor and a mischievous ghost. The supplied premise points to a light supernatural setup rather than a frightening horror story, with the emphasis on laughter, unexpected situations and ensemble involvement.

Viewers can expect Ducobu’s school-world characters to share the story with parents, teachers and other Saint-Potache figures. The Halloween setting provides the central seasonal context, while the haunted house and Anatole’s antics drive the film’s mystery and comic complications.
