In 2008, young policewoman Liang Nanxi crashed her car while pursuing a vicious serial killer and ended up in a coma.
But her consciousness appeared inside a young female tourist on a tour bus heading to Da'an Mountain in 2018.
Heavy snow sealed off the mountain, trapping the twenty people on the tour, including the guide and driver, in a hotel halfway up the slope.
That night, a little girl in the group died under mysterious circumstances. The girl's father was Xiang Bonian, Liang Nanxi's boyfriend. To find the killer, Xiang Bonian planted a timed bomb in the villa.
“Find the real murderer who killed my daughter within four hours, before daybreak! Otherwise, we'll all die together!”
By coincidence, Liang Nanxi discovered that the girl's death was identical to the serial killer's method of killing, the very killer she had been pursuing.
