You're Telling Me the Killer Was Already Dead Before the Murder?

Winter 2013, Room 201, Building 3, Sui'an Road.

In a sealed room, three people die in three completely different ways:

Sleeping pills, pesticide, and a fruit knife.

There are no signs of a struggle or forced entry. Every object sits in a silence that feels all wrong.

Three people, yet all meet the same end.

The only survivor is a four-year-old girl.

Tears cling to the corners of her eyes, and traces of sleeping-pill powder remain at her lips.

Rookie police officer Ye Chen stumbles into the case, and together with Lei Ming, the “mailroom security guard,” gets drawn into this silent maze.

No witnesses, no suspects, no signs of a struggle, and no clear motive for murder.

The only clue is a set of inexplicable footsteps.

Those footsteps come to an abrupt halt in the cold darkness.

Meanwhile, a cold case from eighteen years ago resurfaces. In 1995, the Zhang brothers were murdered, and one of their bodies has never been found.

After confessing, the killer, Li Weiguo, dies under mysterious circumstances. Yet the forensic report places his time of death before the murders took place.

Two eras, two murder cases, and a group of ordinary people swept along by the tides of their time, struggling to survive on this land.

As the clues are pieced together one by one, new questions keep arising.

An even greater secret remains frozen beneath the ice.
