Fu Yixuan accidentally discovered that there was a ghost in the movie theater who could play a murderous piano piece. The ghost was elusive, and with its appearance, many unidentified soldiers who had been sealed in the movie theater for a long time appeared, watching movies, smoking, and making a racket, before vanishing into thin air in an instant.
After infiltrating the movie theater again, Fu Yixuan was shocked to see a photo of his grandfather from his youth on the wall, and the story told by the ghost was even more terrifying—later, from his grandfather, Fu Yixuan was astonished to hear that the ghost had already died on the battlefield.
Why did General Kong, the ghost, fall from the fourth floor and suddenly disappear? Where did the sound of artillery outside the movie theater come from? Why is the tragedy on the battlefield shrouded in smoke and fire repeated every day?
What curse has befallen those who died and came back to life, only to die again? In their investigation after investigation, Fu Yixuan and his partner Anna finally uncovered the mysterious truth of the events.
