Five police officers in Hong Kong are kidnapped. The police commissioner is on a business trip overseas. Two vice commissioners, Sean Rau and M.B. Lee, then take over the case. The two vice commissioners are rivals who both vie for the police commissioner seat. At first, M.B. Lee takes the lead in the case, but comes to a dead end.

When Ar realizes that Mung's dragging her sister (Law regular Pinky Cheung) with him, she joins forces with the vegetarian vampires to fight their common enemy.
