Number One (1973)

(1973) 
Summary
Welcome to "Number One". Benni (Chris Avram), the owner of a photo agency, arrives. He welcomes Leo (Venantino Venantini), the owner of the club, Sylvie Boisset (Claude Jade), a French actress and model, Mino Cattani (Massimo Serato), the editor of the newspaper, Commenda (Renato Turi) and the lawyer (Paolo di Tusco). There is a lot of murmuring and the editor of the newspaper receives a phone call. He is nervous and whispers to Leo and makes another phone call. Sylvie observes the men's interactions. At dawn in a villa in Rome: three men sit next to the body of the naked Deborah Garner (Josiane Tanzilli). Her sad husband Teddy Garner Jr (Paolo Malco) is comforted by his two friends: Massimo (Guido Mannari) and Dino Pancati (Howard Ross). Shortly after, a doctor, the Doctor (Andrea Aureli), arrives. He diagnoses the death and has Deborah taken away. Teddy immediately leaves Rome. Dino and Massimo go to the Capannelle, where they meet Pupo (Bruno Di Luia), the leader of a gang.
Inspector Vinci (Renzo Montagnani) starts investigating the Deborah Garner case. He interrogates all the members of Garner's entourage. The Commendatore tells him that Garner is close to a royal family, the elderly Princess (Rina Franchetti) says nothing, the lawyer turns to an art dealer (Roberto D'Ettorre Piazzoli) who is involved in the trade of stolen paintings, as well as to the director of a pawnshop who is also an accomplice. Now the case of the stolen paintings has to be investigated. Vinci now works together with the Captain (Luigi Pistilli), the commander of the Carabinieri.
The commendatore elaborates a scam with the notary: he pretends to have bought some paintings from the legitimate owner, now deceased, a nobleman, which then ended up in Garner's house. He negotiates with the accountant (Guido Lollobrigida). There he receives a call from Pupo, who has been ordered to punish a married couple who have taken out a loan with false cheques. The husband (Andrea Scotti) is beaten, the wife (Rita Calderoni) is forced to have sex and raped by Pupo.
Nobody shows up at Debora's funeral except Sylvie, who is identified by two policemen. Sylvie calls the Carabinieri and gives them a tip-off: there are paintings stolen from the convent of Monterenzo. The carabinieri, led by the captain, find the paintings in the Monterenzo monastery and arrest the prior.
When Sylvie returns home, Inspector Vinci is already waiting outside the door of her flat and questions Sylvie's neighbour. Sylvie runs away from the house.
Sylvie is visited by Benni during the night, who makes a phone call to someone called Rudy. Sylvie finds the phone call suspicious in connection with Deborah's death, the death of an American nobleman and the theft of art.
Sylvie now goes to see Massimo, who lives with his wife Betsy (Isabelle de Valvert), a model. Sylvie confides in Massimo and tells him that Benni received a phone call in his presence from the nobleman Rudy, who was involved in the theft of his uncle's painting and was in "Number One" during the theft so that the Commendatore would tear up some bills for his complicity in the theft. Later, the uncle is eliminated. Massimo confides to Sylvie how he, along with Dino, Pupo and other crooks, had taken the paintings to the monastery. Leo was also at the scene, Massimo reveals. Massimo tells Sylvie not to be too afraid of Benni because the real criminals and dangerous villains are Leo and the Commenda.
After the Captain interrogates the Commendatore, Sylvie enters his office. She is anxious and confides in him that she knows the true story of Deborah's death: In a flashback, narrated by Sylvie, we see Deborah's agony and death. She has taken the heroin and is rolling around naked ecstatically in agony on the bed, helpfully caressing herself with white foam in her mouth. Dino and Massimo advise Teddy not to save her, but to allow her inevitable death. Because the two had planned an expensive divorce. Since death takes a long time, the men play cards until Deborah is finally dead after a long agony. Because she is late, they bring the situation to Leo's attention. Leo turns to the editor and sends the three men a doctor he trusts, who ascertains Deborah's death. Sylvie tells the Captain that she is worried about Massimo. She has not heard from him for four days and he has disappeared. The Captain thanks Sylvie and asks her to make herself available, because she can tip off the plot...
The Captain arrests Dino at a poker club. The latter admits that the cocaine found in the Garner house belongs to him. He ends up in prison, where we see him as an altar boy. Massimo learns of Dino's arrest and is frightened. While having sex with Betsy, he tells her that a policeman (Emilio Bonucci) showed up while he was carrying paintings on the beach at night. The policeman was first shot and then had his throat slit. Now he wants to escape to Switzerland with Betsy. He calls his friends and asks them for money. These friends tell him to come with Betsy to a lake, the Lake Martignano. Massimo and Betsy can't wait to get all the money. Massimo is doing a photo shoot with Betsy on the shore of the lake when the two are suddenly executed with many gunshots. Both are dead.
On the way, a car stops next to Sylvie. Pupo jumps out, hits Sylvie and drags her into the car. The car drives away at great speed. A short time later, Pupo and his gang are eliminated by a group of assassins. They had just learned that an autopsy had been ordered on Debora to determine the true cause of death. The Captain leads Benni to the morgue where a female corpse is found. Benni says he can't recognise her as Sylvie. The Capitano says he will keep looking for Sylvie Boisset, because he is only interested in what happened to her. Benni gets nervous, makes a phone call and threatens the caller. A bomb explodes at Number One. Then a car explodes. It turns out to have been used to transport stolen paintings. Publisher Cattani's newspaper publishes an article on the death of Massimo and Betsy: double suicide. There are no more witnesses. The two investigators attend the exhumation and discover they have no evidence against anyone.
