A child, left unsupervised by their parents while playing around the hallway of their apartment, wanders toward an elevator that holds a dark mystery within. Inside lies a supernatural toy doll, a medium used to summon spirits and invite them to play. Suddenly, the doll seems to come alive, welcoming the child and inviting them to play. Jelangkung!

Jelangkung is a traditional Indonesian spirit-summoning doll used as a medium to call upon spirits and invite them to play. This eerie concept is inspired by Indonesian folklore and horror traditions.
