Cobb opened the safe and picked up the confidential papers, only to be arrested. In order to save his companions, he had to give up the gun in his hand. However, this is just a dream. To distinguish reality from dreams, they carry a totem with them. Cobb's totem is a spinning top, and if the top keeps spinning, it indicates that he is still in a dream; If the top stops turning, it indicates that he is in reality.
Through their investigation, they found that the father-son relationship between the elder Fisher and the little Fisher was the key. In life, Fairhouse Junior has not been recognized by his father, so he is frustrated. If nothing else, Faircher Jr. will inherit the family business and carry it forward. Cobb and others' plan is to implant ideas in Fisher Jr., making him think that Fisher Sr. has been busy with his career all his life and has no time to spend with his family, hoping that he can live the life he wants. The plan is well underway. Suddenly came the news of the death of the old Fisher, and the younger Fisher would go to mourn. Cobb and others decided to expose the will during their condolences. In order to facilitate the purchase of the entire airline, Saito decided to go on a dream raid after boarding the board at the tip Fisher. However, Lina is upset because Cobb feels guilty about his wife's death.
In Cobb's subconscious, the wife would appear in dreams from time to time, interfering with their plans. Cobb couldn't control her behavior, which became a destabilizing factor. On the plane, except for Tip Fisher, all the others were members of the Inception team. Cobb took the opportunity to talk to Tip Fisher and put a hypnotic potion in his drinking water. Through the dream sharer, they are successfully connected together. The plan began, and they entered the first level of dreamland. Here they need to face kidnappings and attacks from defenders. In the city, a large train approached and directly scattered their ranks. It turns out that this is the defender that Tip Fisher subconsciously generated. They managed to escape danger, only to discover that their employer, Saito, had been injured. Cobb decides to let everyone send Saito home and then go home again. This time, they need to ingest a lot of sedatives, otherwise they will be trapped in the maze once they die in the dream.
It was the most chaotic dream, as if in the dark void, and even mental breakdown in severe cases. They take advantage of the difference in the time flow rate of dreams to allow Kato to be relieved in the second layer of dreams. In order to enter the second level of dreams as soon as possible, they disguise themselves as Fisher Jr.'s uncle, hint at the password of his will safe, and force him to make up a string of passwords.
In the second level of dreams, they successfully steal information, but when retreating, they encounter guards. To get rid of the guards, they had to look for exits. Cobb managed to find the exit, and the rest of the team escaped. Cobb returned home to find his wife gone. He felt lost, but also realized he needed to work harder to protect his family and the success of his program.
