Guided by their shared passion for exploring ruins, the 5-member team, known as “Beneath the Ruins,” embarks on volunteer missions that unexpectedly unveil a series of mysterious and chilling events. Across various ruins in Taiwan, they encounter ghostly spirits unaware of the long-gone Japanese troops, a little girl who vanishes from a bathhouse, and the eerie presence of hundreds of eyes in a dark, abandoned mine shaft. These spine-chilling encounters give the team members insight into the stories behind the lingering spirits that remain within these ruins. Despite each member concealing their past, a mysterious force draws them together. What awaits them behind the overgrown grass and decrepit doors? Are there only mysteries and dangers? Or do they offer a second chance for redemption? Will the team members be able to face the shadows of their past and unlock unforeseen possibilities?
