Kwok, an archaeologist, Paul Chung Fat leads two students on a quest for ancient artifacts and stumbles upon a cave where three jiangshi—an adult male, an adult female, and a male child—lie immobilized by talismans glued to their foreheads. Kwok brings them back to his lab and plans to sell the boy vampire on the black market, a decision that sets a dangerous chain of events in motion.
During transport, a careless move strips the talisman from the boy’s forehead, breaking the charm. The awakened creature escapes and happens upon a house, where it befriends a young girl who mistakes the strange boy for an illegal immigrant. Meanwhile, in the lab, one of Kwok’s students mischievously removes the talismans from the adult vampires as well, reviving them. The revived vampires begin to hop around, attacking people, and it takes all three men some effort to subdue them again, keeping the danger just at bay for the moment.
One of Kwok’s students is bitten by the male vampire during the struggle, so the bitten student seeks treatment from Dr Lam. Lam Ching-Ying plays this Doctor, who, along with his daughter Gigi Moon Lee Choi-Fung and his prospective son-in-law Yen Yuen Biao, sets out to wipe out the vampires that are now loose in town.
Lam orders Yen and Gigi to secretly shadow Kwok’s student and locate the vampires. While Gigi goes to alert the police, Yen accidentally removes the talismans on the foreheads of the vampires, waking them once more. Lam and Gigi arrive to help, and after a sustained confrontation, the group sedates the vampires with lab sedatives. The police soon arrive and transport the two vampires to the morgue at the police station.
Lam and Yen then sneak into the morgue and attempt to kill the vampires with a wooden sword, but their plan fails. Kwok and his students arrive at the morgue as well—the student needs a sample of vampire blood to cure himself after the bite—and the group must improvise a way to move the vampires out safely. Disguising themselves as corpses, they haul the vampires out and load them into the back of a truck, with Lam and Yen taking the driver’s seat to hijack the vehicle.
A roadblock stops them, and the two vampires escape again. The boy vampire, hearing news of the sighting, cries out loudly, alerting the others to the location. Lam and Yen catch wind of fresh vampire sightings on the radio and rush to a nearby children’s home. With police assistance, the two adult vampires are killed, but Yen spares the boy vampire after seeing how fond the children have grown of it. He dresses the creature in ordinary clothes and slips it away, evading police attention.
Kwok arrives just as the plan unfolds, collapsing to the ground. His students reveal a dark twist: they have become vampires themselves after failing to secure a vampire blood sample to cure their bite, leaving Kwok and the others faced with a new, unsettled danger.
