Xiao Tang (played by Poi Song Na Lin) and rich girl Katie (played by Cha Su Ti Da) are good friends who grew up together. They often play the most popular augmented reality mobile game with their friend Tai Duo. Once, Xiao Tang boldly played the game in an abandoned building and accidentally took a photo of a "ghost", which made her run away in panic. After she told Katie, the two decided to send the ghost photo to their friends, hoping that others would also try their courage and treat it as a prank. However, they did not know that this terrifying photo, which later became wildly circulated, would hurt themselves and their friends, and even kill people. Don and Katie must solve all the problems as soon as possible. At this time, Katie finds out that her boyfriend is having an affair with Don, which puts their friendship in danger of breaking down. But at the same time, they have to face their common fear: solve the ghost photo, otherwise the "ghost in the photo" will come back to destroy everything they have.
