The dead follow the road back, and the unknown borrows the road to come.
After his grandmother passed away, communications engineer Zhou Yan returned to his hometown in southwest Yunnan for the funeral.
On the first seven nights, someone in the back mountain called him by his childhood nickname.
First, grandma.
Then there's the mother.
Finally, it became his own voice.
"You're back."
"What about me?"
What's even more strange is that a communication base station on the mountain that has been offline for seven years will come back online for a full 137 seconds every 2:17.
And that terminal that shouldn't exist actually used the SIM card that grandma had deactivated for many years.
As the investigation deepened, Zhou Yan found another video from twenty years ago.
In the video, the seven-year-old boy was taken home by his mother.
But at the end of the camera, there is a child wearing the same red dress, walking home step by step along the mountain road.
And the old files show——
Zhou Yan died once twenty years ago.
Calling names in the mountains, calling souls, ghosts beating walls, water ghost substitutes, Nuo noodles, driving away corpses...
The stories that have been passed down for hundreds of years all seem to be telling the same thing.
Dead people follow their own path.
But Zhou Yan must figure it out:
Who was the one who was called back?
