Voss, Nevin, Ryan (Quentin calls him Lance), holloway and Quentin are five strangers. When they woke up, they found themselves in a maze of death traps. They don't know how to get here or where they are. The rooms inside are exactly the same. Everyone avoids all kinds of traps and realizes that they must work towards the same goal, that is, trying to escape. ? Among them, Quentin is a strong policeman, Ryan is an elderly jailbreak expert and sensor expert, holloway is a social activist and doctor, Voss is an architect, and Nevin is a young student studying mathematics. Ryan died first in the next test. Nevin was clever enough to find a password scheme to let them escape. After a long time, they found that Kazan had some mental retardation. At this time, Quentin's cruel nature is undoubtedly exposed. He thinks Kazan is a burden and wants to abandon him. But holloway, who is kind-hearted, tried every means to obstruct it, which left Kazan. Later, in the conflict with Quentin, Voss revealed that he knew they were trapped in a cube, and the shell of the cube was designed by himself. ? During the trip, holloway had a big fight because Kazan almost killed Quentin. After that, the team finally found a way to reach the edge of the cube, but it was just a crack between the cube and the shell. Holloway volunteered to find the exit on the wall, and everyone tied her up with clothes. Suddenly she bumped into something and the rope fell off at once. Quentin immediately pulled it to the rope. When she was pulled back, Quentin insidiously wanted to use Hogwarts' body to test the falling time and calculate the height of the cube, so he let go and holloway fell headlong ... Naiwen was depressed and asked for a rest. Quentin also reluctantly agreed. When they were asleep, Quentin secretly took Voss' shoes and carried Nevin into the next room. Nevin disagreed. Quentin meanly tried to rape Nevin and force her to agree. Suddenly Voss woke up and rushed in with Kazan to stop Quentin. Voss was beaten by Quentin. At this time, Nevin and Voss finally recognized Quentin's ugly face. ? Quentin left Voss in the room below and was about to tidy up Nevin when Voss' laughter came from the room below. They followed, just to find Ryan, who was corroded by chemicals at first, and later found that they were circling. Quentin saw all this and was desperate, but Voss suddenly remembered something. He went back to the gap of the cube and suddenly found that they were not circling, but the room was circling. This explains why they often hear the sound of collisions. Clever Nevin also found through calculation that they need to go back to Room 26, and this cube is 26*26*26, so that room is just outside the cube, which is equivalent to a ship that will carry them to the other side. But Neven also found that judging whether there is an organ in the room requires a lot of astronomical figures, and no one can do this. At this time, Kazan inadvertently said 2, which caught their attention. Only then did he discover that Kazan was a gifted mathematician with low intelligence. He could immediately name an astronomical factor, so they bypassed the room with authority by Kazan. On the way, Nevin and Voss designed to throw Quentin into the cube. After a series of tossing and turning, Nevin and Voss finally found the exit and saw the light again. When they were ready to escape from the Rubik's Cube, Voss gave up going out. When Nevin persuaded him, Quentin suddenly appeared and he killed Nevin. Voss wrestled with Quentin and shouted Kazan out. Of course Voss couldn't beat Quentin, and Kazan quit. Quentin has caught Kazan, and half of his body has gone out. But when he wanted to go out, he couldn't get out. He turned his head and found that Voss clung to Quentin's feet, stalling for time, the cube they were moving was also moved to the point, and Quentin might be dismembered. Katyn is the only one among several people.
