The plot of "The Invisible Guest" is very brain-burning, how can I understand it?

"The Invisible Guest" is directed by Oriol Paul and stars Mario Casas, Ana Wagner, Barbara Lanni, and Jose Coronado Suspense movie. The film was released in Spain in January 2017. Since the continuous reversals make it more difficult to understand, I have sorted out some key reversals, which are the most brain-burning parts of the film. Let's take a look.

Cause:

A secret room murder case. The entrepreneur, the male protagonist Doria, claimed to be having a tryst with his lover Laura, but was discovered and the other party extorted 100,000 yuan. After the two rushed to the hotel for the appointment, the male protagonist was knocked unconscious. When he woke up, he found that Laura had been killed and the money was scattered on the floor. The police subsequently arrested him. It was a sealed room, the window bolts were unplugged and could not be opened, and the door was locked. Since the police had no direct evidence and had not arrested the hero yet, the hero's assistant recommended Goodman, a lawyer with a high winning rate, to the hero. Goodman arrived at the hero's house three hours earlier than the agreed time for discussions.

Reversal 1:

Lawyer Goodman pointed out that they have found unfavorable prosecution witnesses, and the prosecution witnesses are about to go to see the judge, and the male protagonist may go to court within three hours court.

The male protagonist thinks in his heart that the prosecution witness may be a passing driver. He told Doria about a car accident that had happened before. During a tryst with his lover Laura, the male protagonist lied to his wife that he was in Paris. On the way home, the two had a conflict over whether to continue the relationship. The two accidentally crashed into a passing car. The victim Daniel had already died. die.

Later, the lover Laura refused to call the police. The two worked together to deceive a driver who was passing by and wanted to help. The lover put the victim's mobile phone in his pocket. Afterwards, the lover waited for rescue and asked the hero to push the car into the water. Soon an old man came and towed the hero's car home for repairs. The couple invited Laura to dinner, and the lover was disturbed because Daniel's cell phone rang in his pocket. Suspecting that the couple turned out to be the victim's parents, Laura left in a hurry, then picked up the hero and agreed not to see each other again.

The male protagonist destroyed the car, reported it to the police that the car had been stolen, and falsified the record of having been to Paris. After a while, his father Thomas called the police, and the police launched a search, and the male protagonist erased the evidence of the crime. The lover creates the illusion that the victim is absconding with the money. The lawyer took out a newspaper photo (the photo showed the mother at the hotel where the male protagonist was framed). From this, the lawyer deduced that the victim's father used the victim's mother's connections to sneak into the hotel and kill his lover, and then escaped through the window. If the hero is to be freed from guilt, he must blame Thomas for Laura's death, which means that Daniel's case must be admitted. Later, the lawyer answered the phone and said that the prosecution witness was a passing driver. At this time, they must blame Daniel's death entirely on his lover. The hero must tell the location of the sunken car in order to forge evidence.

Reversal 2:

The male protagonist said that he was not unconscious, but just wanted to hear the lawyer's explanation, and admitted that the victim was not dead at the time. The lawyer assumed that it was the male protagonist who took Daniel's wallet and forged transfer records, and it was he who prevented his lover from calling the police. In extreme pain, Laura told the victim's parents the truth, pretended that the matter was revealed, and asked the male protagonist to a hotel to use it for money. Make up for the two parents and persuade the male protagonist to surrender. The male protagonist refused and killed Laura to make it look like he was being framed. The male protagonist denied this hypothesis and asked his parents why they didn't go to the police. The lawyer believed that they had already lost trust in the police. He opened the curtains and could see the victim's father staring at the room where the male protagonist was from the same floor in the opposite building. The lawyer said that he investigated the victim's father and learned everything about Daniel.

Reversal 3:

The male protagonist still denied that he had killed two people in a row, took out the photos, and believed that his hypothesis about the victim’s father’s murder was completely reasonable. At this time, the lawyer pointed out The photo was fake and there was no reflection of the victim's mother in the mirror. The male protagonist admitted that he killed Laura. The lawyer's hypothesis was established and he drew the location where the body was buried.

Reversal 4:

The two reached an agreement. At this time, the assistant called and said that the male protagonist’s mobile phone had been turned off. The lawyer asked to take a break, and the male protagonist took the mobile phone and turned it on. I heard that my assistant had bribed the passing driver.

There was a sound of electricity coming from the male protagonist's cell phone, and the pen in his breast pocket leaked ink. The male protagonist put the pen on the table and found a message from the lawyer - "No one is going to see you." The judge, there were no prosecution witnesses, and all the information was made up.

"Opening the pen, he found that it had been tampered with and turned into a recording pen. At this time, the male protagonist realized that he had been deceived. In fact, the lawyer who arrived early was the victim's mother, who was disguised as lawyer Goodman. The key clues were obtained. Three hours later, the real lawyer Goodman arrived. The victim's parents on the same floor in the opposite building looked at him and called the police station.

In fact, The constant reversal of this movie also hints at the reversal of people's hearts and the darkness and coldness of human nature. It is precisely because of the many reversals that the plot is brain-burning. How to understand this movie: watch it. After finishing this answer, watch the movie a few more times.
