A skeleton from the closet (but not enough skeleton)

While Jessica is having sex with a casual lover, she hears her husband Horace coming. So, she runs to him and takes him outside to give her lover a chance to escape. Instead, he hides in the closet, gets stuck by the faulty lock, and dies of asphyxiation. That night Bozo, while burglarizing her apartment, in the bedroom forces the closet and is overwhelmed by the man's naked body, thus collapsing to the floor unconscious. The noise wakes Jessica, who is in shock, tears in her eyes, pulse racing. Horace sleeps by her side, and she absolutely does not want him to know. So, she has two bodies to disappear before he wakes up. She asks her friend Daria, who lives in the same building, and her boyfriend Walter, the young scion of a well-known surgeon and himself a pathology student, for help. The three take the two bodies away, leave Bozo unconscious in a public park, and Walter takes on the task of throwing the body into the river. But he is in the midst of an experimental dissertation, and does not want to miss the opportunity of a body all to himself to be dissected in his father's private clinic. Horace is an abstract and currently cash-strapped artist, waiting for a life-changing inheritance, who survives by drawing Picasso-style police sketches. He therefore has an adversarial relationship with inspector Brumby, who prefers the figurative style and doubts that sketches with two noses and three eyes are useful in capturing wanted men. What's more, for months he has also been working on the statue to the Unknown Policeman, a prestigious commission of the Police Headquarters to be inaugurated soon. Unfortunately, however, after a final embarrassing sketch that causes the inspector a diplomatic incident with the commissioner, Horace is fired on the spot. Frustrated and misunderstood, in anger he destroys the statue to the Unknown Policeman, and collects its rubble in a sack. But after throwing it off the bridge over the river at night, he is stopped by a Policeman himself, who fines him and takes down his personal details. Shortly before from that same bridge Walter had thrown, unseen, a sack with the human remains of Jessica's lover after his experiments. Jessica meanwhile, after the shock of the two bodies in the house, must also fend off attempts to blackmail from Bozo who, even he was half-unconscious that night, is aware of her secret. Therefore, she decides to consult with Daria to work out a strategy, in a confidential place: the riverbank. But right there the two friends make the macabre discovery. On the shoreline is the severed head of her dead lover. Horrified, they run away in tears, mad as hell at Walter, who betrayed their trust. Brumby is an eccentric inspector, a misfit at the Police Headquarters, who prefers solving crossword puzzles rather than investigative cases, has no deductive logic and cannot stand the sight of blood. So, for him the inspection on the found head is a torture, and he gladly outsources it to his trusty assistant Caputo, who has a strong stomach. The latter knows the chief's weakness; he knows how much it repulses him bringing that macabre find to Police Headquarters. Thus, he asks his permission to take it home to collect it under formalin. He used to collect beer caps from all over the world, it was a real trauma when his wife threw them away, and he is convinced she won’t touch a collection of human heads. Horace is not a lucky man. In fact, from the found remains of the corpse and the fine for dumping the sack in the river, he is suspected of murder and dissection, much to the delight of Brumby, who can take revenge for his eccentricities as a drawer. But the thief Bozo is not a lucky man either. In fact in a new night raid he goes to steal right into Caputo's house, finds the same dead man of the closet, but this time only his head under glass, he faints again, and is thus arrested. In jail Horace makes acquaintance with Bozo, they tell each other their misfortunes, so the artist reconstructs what happened, and has the evidence to be released, while Jessica, Daria and Walter are investigated. Subjected to interrogation in Brumby's office, the three friends take advantage of his mental fogginess, while confuses crossword puzzle definitions with the investigations report, not to mention the fascination that the winking Jessica exerts on him and Caputo. Thus, the three friends get away with house arrests, while a dispute arises between the two inquisitors that verges on a rustic duel, with a final surprise.
