O Rebu

A police siren breaks the silence of Alto da Tijuca on a Sunday morning, stopping at the door of a large mansion. Inside, the guests at a large party hosted by a banker await the police officers who have begun investigating a mysterious death that occurred during the reception, with the victim's body being found in the house's pool. A police case divided into two periods. The present, the story of the investigations, and the past, with flashbacks of each character, showing their life and the reasons that led them to attend the party hosted for an Italian princess.

Arriving at a luxurious mansion in Alto da Tijuca, when the day is still beginning, Police Chief Xavier begins to investigate a mysterious death that occurred during a reception offered to Princess Olimpia, an Italian noblewoman who is in Rio representing some industries. After removing the body from the pool, the police chief sees that it is useless to try to obtain any information from the owner of the house, the banker Mahler, and begins to question Ana Lúcia, who is responsible for organizing the party and is used to preparing receptions for high society like this one. Explaining that the princess wanted to meet Brazilians, she gathered thirty people, including bankers, artists and athletes for the party, but believes that none of them would be capable of committing a crime. One of the first to arrive at the party was Boneco, a vulgar thief, specialized in seducing maids to break into his boss's house, who soon has his attention turned to Maria Angélica, a rich widow who still has romantic hopes. Boneco entered with a stolen invitation. Then Silvia, the former girlfriend of Cauê, Mahler's adopted son, arrives. Also among the guests is Braga and his wife, Mahler's biggest competitor in the business world. After arguing with Silvia, since Mahler does not approve of the relationship, Cauê goes to meet Kiko, who is trying to get money for his business through Lupe, to warn him about the dangers he runs by getting involved with her.

Checking the guest list with Ana Lúcia, the Police Chief soon discovers a mysterious representative of Mr. Morone and, after a phone call, confirms that he had not sent anyone in his place. Talking to Cauê, Kiko reveals that despite fearing Lupe's aggressive nature, he has already devised a way to escape from her when he gets the money for his business. Discovering Boneco searching one of the rooms in the mansion, Maria Angélica thinks he was looking for a romantic place to meet her, but Boneco manages to escape. Talking about the party, the employees begin to believe that Boneco, like Wilson, Morel and Fininho, is a member of Princess Olimpia's security. Looking for Silvia, Cauê reveals that he left her under pressure from Mahler and recalls the violent fight he had with his adoptive father shortly before traveling to Italy. Later, Cauê becomes irritated when he notices that Alvaro is hanging out with Silvia. Talking to Kiko, Helena reveals that her husband is on the verge of a schizophrenic crisis, of a violent nature, and for this reason he is afraid of separating. Shortly after speaking with Laio, Helena becomes more worried when he claims he knows everything about her.

Continuing his investigation, the police chief focuses his suspicions on Mr. Morone's fake representative, listening to the waiters who found his behavior and way of speaking, full of slang, strange, in addition to provoking all the women at the party. Finally, listening to Lurdes, he discovers that the man's name was Boneco. In a parallel investigation, Wilson, Morel and Fininho discover that the body was dragged from the library to the house's pool, and Fininho remembers that he saw Boneco talking to Braga in that room. Interrupting Silvia's conversation with Cauê, Mahler goes to introduce his adopted son to Princess Olimpia. Remembering that he started living with Mahler when he suffered an accident playing polo, Cauê also remembers that he always preferred to keep his relationship with Silvia and the trip he took to Europe secret, against his will. Going to meet Silvia, Alvaro is disappointed when she refuses to accept that he reveals their relationship. Talking to his wife, Laio says that he also knows everything about Mahler and Braga's dealings. Calling Silvia to walk in the garden, Braga asks if she wants to win a million cruzeiros.

Talking to Ana Lúcia, despite avoiding involving any of the guests, the police chief discovers that Braga was the man who was talking to Boneco in the house's library, where Princess Olimpia's security personnel believe the crime scene was. Later, she also reveals to the police chief that she was very scared when she saw Laio kill a parakeet in the garden's aviary. Talking to the princess, Cauê soon manages to win her over, to the delight of Mahler, who is also worried about Braga, his competitor in the purchase of Bancos Reunidos, and asks Álvaro to keep an eye on his guest. Talking to Braga, Silvia learns that he wants to know Mahler's proposal for the purchase of the Bank and in exchange for one and a half million cruzeiros, he promises to get the information through Álvaro, thinking of getting Cauê's freedom with the money. During the conversation, Silvia remembers that Cauê was a poor boy who managed to socialize thanks to his skill as a polo player and now, as Mahler's protégé, is being dominated by the banker. Suspicious that everyone is against his project to obtain the concession of shipyards in Recife, Laio believes he is being followed and when he enters the bathroom and sees Boneco stealing perfume, he tries to attack him, saying that he is doing it to poison him, forcing the thief to use violence to escape.
