Antikalpa introduces mysterious Taoism traditions and rituals to a chilling stage for the opposing forces of gods and demons.

Ah Dai comes from a family that runs a prestigious orthodox temple. His childhood sweetheart, Yufan, is desperate to locate her missing aunt. In his attempt to help, Ah Dai agrees to participate in a special ritual that his schoolmates believe could help them seek assistance from the gods to grant their desires.

At the very end, he faces a completely demonized Yufan and must fight her to save the neighborhood.
