Ken is a bit stuttering, loves small animals, and also likes to raise fish, and he named his favorite fish "Wanda". As Wanda's elder brother, Otto knows Ken's mind well, so he fights against him everywhere.
Although the atmosphere was very tense when they committed the crime, they were shocked and unpredictable, and the diamonds were successfully obtained. But when they evacuated the scene after committing the crime, an old woman recognized George and became a witness. In order to kill her, George ordered Ken to kill her, but the dog bit, car crashed, box smashed, failed three times, only three dogs died. Ken likes animals. The puppy's accidental injury made him distraught. He died of a heart attack to the old woman, but he was gloating and excited.
After the alarm was cleared, they hid the diamond. In order not to attract the attention of the police, they split up and arranged to meet at the airport on Tuesday.
Otto and Wanda are celebrating the success of their greatest sibling partner. Wanda reminded Otto that if they knew he was not her brother, he would be in trouble. So they conspired to sell George to the police. The police arrested George at the address they provided. At this time they discovered that the diamond had been secretly transferred elsewhere by George.
In the prison, George's defense lawyer LeachKrissis understanding the situation. At this time, Wanda and Otto came to visit George. George has become suspicious of Wanda, threatening her that if he feels something is not so satisfactory, he will tell the police who his accomplices are. Wanda and Otto get nothing, Wanda decides to work on Leach, George's lawyer. As George's lawyer, he would know about diamonds, so Wanda wanted to develop a friendly relationship with Leach. George reminded Ken, who came to visit him in prison, not to tell Wanda anything, but to be especially careful about Otto.
Wanda took the initiative to approach Leach in the name of humbly learning legal knowledge, and tried his best to compliment him, in order to inquire into the court's knowledge of the case. Leach was still a little wary at first, but in the end he couldn't withstand Wanda's sexual offensive, which caused Otto's jealousy. Otto warns Wanda to keep her distance from Leach.
Leach takes the opportunity of his wife Wendygo out and have a tryst with Wanda at home. Unexpectedly, Wendy came back early, which caught them off guard. Fortunately, Otto and Wendy, who were hiding outside, were able to get out of the room. On this date, Wanda not only got nothing, but also left the necklace at Leach’s house. The small metal box on the necklace contained the key to open the diamond box. Of course, Wanda was very frustrated. The necklace was discovered by Leach's daughter. Wendy insisted on seeing it. Leach had no choice but to follow the boat and lied that it was a gift to Wendy.
Wanda urged to return the necklace. Leach lied to Wendy that this necklace was entrusted by an 80-year-old woman to engrave it in a jewelry store. The necklace is very emotional, but I don’t know who put it in the merchandise counter by mistake, and the old woman dying. Leach bought a necklace that was three times the price of this one, but Wendy refused to exchange it.
Lichyowanda had a tryst in his friend's apartment, and Wanda brought up the necklace to him again, falsely claiming that it was given to her by her mother before her death. Leach promised to find a way to get it back. Regarding the date between Wanda and Leach, Otto was jealous, always following Wanda like a shadow, and hanging Leach upside down from the window of the five-story building. Wanda was very annoyed by this, calling Otto an idiot and asking him to apologize to Leach, otherwise their plan would be ruined.
In order to get the necklace back, Leach disguised himself as a thief, stealing the necklace while his wife was out. This happened by Otto. He pretended to be his friend Leach catching the thief, covering his head with a pocket, hitting him on the head with a pan, and taunting him from time to time until his wife Wendy came back. Otto escaped.
Otto was forced to tell the diamond hiding place, took the diamond one step ahead, and took Wanda away. Archie rushed to the airport angrily and fought with Otto. Otto almost died under the wheels of Ken who came to retaliate, and watched Archie and Wanda fly together to Rio de Janeiro.
