In a future ruled by super-artificial intelligence "Guardians", emotions are seen as defects that must be eliminated, and mankind's collective dream "Dreamland" is dying and turning into a forgotten wasteland.
Former elite agent Chen Ji is now a dream collector who is heavily in debt to treat his sister's illness. He sneaked into the most dangerous restricted area of the Dream Realm, just to find the legendary Somnambula. However, what he found was a pure dream spirit that should not have existed.
This existence called "Zero" is the only hope to restore the Dream Realm, and it is also the ultimate sample that the rulers are determined to win.
Overnight, Chen Ji became the most wanted criminal in both worlds. On one side is his former partner who represents absolute rationality, leading the Ministry of Order to launch a dragnet-like pursuit; on the other side is the mysterious resistance organization "Dream Weaver" who vows to revive the dream, extending an olive branch to him, but with different purposes.
When the embers of the dream are about to be extinguished, when the human soul is about to be completely formatted, Chen Ji must make a choice. Is what he protects a girl, a world, or the final proof of what makes humans human?
This is a desperate journey caught between reality and fantasy, and it is also an apocalyptic tragedy about memory, emotion and the meaning of existence.
