Gong gui zai

In a big cave an evil dwarf sorcerer is performing a bizarre ritual. Suddenly four righteous sorcerers enter the cave and attack him. In the subsequent struggle they wound the dwarf sorcerer fatally and throw him into a stone coffin. They carefully seal the coffin. The present time: a group of photographers investigate the legend of the evil sorcerer. They enter the cave and break the seal. Red smoke gushes from the coffin and ghastly things start to happen.
