Five Friends

Bagas, Lenni, Dicky, Juna, and Andrew were united when climbing Mount Madyopuro. The climbing post guard warned: the group must be even and it is forbidden to look back or someone will follow. They fail to adhere to the myth, and are haunted along the way. After getting lost until the night of Suro 1, they finally realized that one of the five was not human, and began accusing each other of who was the ghost among them.
