Rust Lake

In 1994, one month before Factory 354, a state-owned industrial enterprise, was restructured and dismantled, three laid-off women who worked at a nightclub were murdered one after another. Their bodies were dumped in wasteland beside Rust Lake. A month later, the factory announced its closure, and the three murders became cold cases.

In 2026, wealthy bachelor Tang Tiansheng is overseeing a real estate project at Factory 354 and has moved back into the employee housing where his parents once lived.

At the project’s groundbreaking ceremony, workers unearth an unidentified skeleton. In an era of turmoil, the old case is once again brought to public attention.

Tang Tiansheng doesn’t take it seriously. He just wants to finish the project as quickly as possible, make his fortune, and leave. But then an old pager beneath his parents’ bed suddenly beeps. The caller is using a brick phone number.

“Hey, give me back my pager, or I’ll kill your whole family.”

“Get my wife, Chen Suyun, on the phone. Who are you?”

“My name is Tang Tiansheng. Chen Suyun is my mother. My father, Tang Yi, died thirty years ago. I miss him. Don’t think you can take his place.”

“Bullshit. I am Tang Yi.”

Wait a minute...

Something is wrong with this world.

A signal transmigrates across thirty years, connecting a father and son who have never met.
