In 2147, quantum tides tore apart the earth, and 30% of the land collapsed into the flickering "ember zone" - where reality and nothingness overlap, and the living and the dead are entangled. The survivor Lin Shen is a "heartstringer": he can read other people's quantum state thoughts and perceive those memories and emotions floating in the superposition state. This ability made him the ace agent of the Bureau of Abnormal Reality (BAR), but it also made him trapped in the noise of countless broken hearts all day long.
When he receives a signal from the Ember Zone, he discovers that it is actually the heartstrings of his daughter Xiaocheng who died in the tide - a call, a quantum echo of memories - he must go deep into the place where reality collapses to uncover the truth about human nature behind the quantum tide. The only ones he can rely on are an AI (Kai) who only wants to follow the drama but is gradually awakening, and a lost warrior (Lu Chen) who is trapped in a time loop and cannot distinguish between reality and illusion.
Can mind readers hear their own hearts? When all timelines converge at one point, the only real thing may not be observation, but entanglement.
