In 1904, Professor Van Helsing travels to China at the invitation of a university in Chungking to lecture on Chinese vampire folklore. He recounts the ancient tale of seven golden-masked vampires who terrorized a village before being banished by a local farmer who destroyed their principal golden bat idol. A young student, Hsi Ching, believes the legend to be true and seeks Van Helsing's help to rescue his ancestral village from the vampires' curse. Joined by his son Leyland, a wealthy widowed Scandinavian woman named Vanessa Buren, and Hsi Ching's martial artist siblings, the group sets out on a perilous journey to confront the undead scourge.

The group faces various supernatural challenges as they travel through the rural and treacherous landscapes of China. They encounter spine-chilling attacks from reanimated corpses controlled by a sinister force. Relying on a blend of Eastern martial arts and Western vampire-hunting techniques, they engage in multiple fierce battles with the bloodthirsty creatures. Together, they must discover the secret to overcoming the undead and bring peace back to the terrorized village. The quest is fraught with danger, testing their courage and resolve as they uncover dark secrets along the way.
