From the liner notes

The story centers on real estate tycoon Wong Ho-Chiu. While sheltered in the luxurious trappings afforded by his wealth and power, he suffers an unbearable loss when his daughter Daisy is kidnapped and killed: a victim of her decadent lifestyle and cocaine addiction. Wong Ho-Chiu turns to his trusted bodyguard Chor to seek out the perpetrators and exact revenge. Chor does his employer’s bidding with an unflinching determination and scarcely contained rage thinly hidden beneath the surface. Wong Ho-Chiu goes one step further and orders Chor to videotape each of their executions, an order to which he complies, revealing the depths of depravity to which he will sink to match hand with his former underworld brethren in his quest for revenge.
