If you could go back in time, would you have the courage to face your initial fears?
Physicist Chen Xu witnessed his loved one lying in a pool of blood. The tremendous grief and self-blame drove him to spend his whole life inventing a "time machine" that could go back to the past.
However, what he thought was the road to redemption turned out to be an endless nightmare.
Every time he traveled through time, he could not prevent death.
In every reincarnation, the murderer is always with him.
Calling the police, hiding, escaping... He tried all methods, but could only watch the tragedy happen again in different ways. Repeating it hundreds of times has wiped out his hope, leaving only numb atonement and exhaustion accumulated hundreds of times with nowhere to talk.
Until the people around him saw through the despair beneath his calm appearance.
In the final reincarnation, he finally mustered up the remaining courage, no longer escaping, and chose to face the cold muzzle of the gun——
He tore off the murderer's mask and saw a truth... He could never have imagined.
It turns out that the deepest despair does not come from the unchangeable past.
But when you go through a lot of hardships and finally find your enemy, you find that there is an unsolvable paradox between you, spanning the entire torrent of time.
An ultimate suspense about time, courage and redemption.
When the gears of the cycle begin to turn, can he break the closed loop of fate?
