In 2028, the alien civilization "Dream Weaver" arrives and drags the consciousness of all mankind into a virtual hell called the "Dream Cage". Here, fears come true, death means brain death, and the only way out is to travel through countless randomly generated and crisis-ridden "door" worlds.
Lin Che, a social animal, woke up in the apocalypse with only one obsession - to find her missing sister. He unexpectedly awakened and gained the ability to sense danger and interpret the rules of dreams. He gathered his partners to survive in the nightmare cycle: the calm former scout Zhao Feng, the gentle medical student Su Xiao, the logic-oriented programmer Wang Lei...
However, they gradually discovered that "Dream Cage" is not a simple killing game. Human emotions are the food of the "Dream Weaver", but the sister Lin Che was looking for so hard turned out to be the manager of the dream world, blocking him with a cold attitude.
Faced with the ultimate choice of protecting her loved ones and saving humanity, Lin Che must tear apart this beautiful lie, even if the price is eternal destruction.
