Escamillo harbours a tapeworm in his stomach – a particularly demanding one at that. This parasite, drawn by the enticing smell of every mouthful, leaps out of its host’s mouth, pounces on its prey and carries it off to its lair to devour it. To rid himself of this troublesome guest, Escamillo goes to see an expert doctor, who prescribes some pills. However, whilst Escamillo is asleep, the parasite, driven by its insatiable hunger, takes a stroll through the dining room.
