Bagas, Lenny, Dickie, Juna and Andrew travel together when climbing Mount Mayopuro. The guard at the mountaineering post warned: the team must stay in line and not look back, otherwise someone will follow them. They did not follow the myth and were haunted by ghosts along the way. Lost until the night of Suro 1, they finally realized that one of the five was not human, and began to accuse each other of who was the ghost among them.
