"Oxide Pang's Bite Till Die series of films"
Similar to Oxide Pang's Hong Kong thriller The Detective, the Bite Till Die series revolves around a private detective agency run by Dragonhair. The former mercenary investigates various mysterious cases along with his martial arts-adept assistant Gene and tomboyish adopted daughter Anna. This time in Killing Box, Dragonhair has barely had the chance to bask in the happiness of his daughter's return from Japan when bullets and a bomb-like box come flying his way. The incidents seem to be connected with Dragonhair's shady past, but it may be his daughter who ends up paying for his past trespasses.
