In the medieval abbey of St. Tiltone da Norcia, the gluttony Friar Lilloncius doesn't submit to the veto of keeping his hands off the mimosa cake as a punishment for having eaten ten more pastries during the day, and throws himself on it voraciously during the dinner.

Inspector Guglielmo de Baskerlillo is called to investigate, revealing that this long tradition of not solving cases can be traced back to the Middle Ages.

As the two policemen realize the potion's effects are brief, they realize as well that the thief will get there to steal it back, something that promptly happens. All that's left for Lillo to do is to discover the identity of the criminal, so he steps in to do so, to no result.
A psychopath known as the Sausage Maniac surprises people at night and forces them to eat enormous quantities of sausages. Intrigued by the case, Inspector Lillo decides to go out on a night walk to capture the criminal, actually hoping to be captured himself and fed with tons of sausages. However, just as Lillo leaves the police station, the maniac walks in and makes Lt. Makobson his victim instead. Once the disappointed Lillo comes back to find out about this, the dubiously qualified criminal psychologist Dr. Past Froll appears to trace a mental profile of the maniac, apparently the victim of a trauma when, as a kid, he had been forced by a grocer father to consume huge portions of meat. Lillo narrows the search to three grocers and enjoys very much all the meat eating coming along with the investigation, even if nothing else comes out of it.
