At 2:14 a.m., the lights in Baichuan's Old Town always go out for thirteen seconds.
Electrician Chen Fang receives a repair ticket from thirteen years ago. The address is 17 Huai Shu Street, but the person who reported the fault has long since died.
There is a light there that should not be on, a bronze badge inscribed "Night Patrol 043, Chen Yong," and a person in blue work clothes with his father's face.
Borrow the light for thirteen seconds, and he can see those the city has forgotten. The price is losing his most precious memories.
His father, missing for thirteen years, is still trapped in the main switch room. A replacement has begun taking over his name, work badge, and life. Before the Old Town goes dark for good, Chen Fang must find the answer:
Will he bring the lost back home, or protect those who are still alive?
