Tuff Part IV - Harvest of Blood

Jiro, a freelancer working at a delivery pizza shop, witnesses the brilliant killing techniques of professional assassin Nejime at a gangster's office where he makes deliveries. Jiro rescues the wounded Nejime and volunteers to become his apprentice. From that day on, Jiro learns the art of killing in a dog eats dog world.

Jiro is a rookie hitman. One day, his mentor dies a brutal death. Furthermore, the execution scene was filmed and leaked as a murder video. Jiro is furious and decides to take revenge. He sets out to track down the mastermind and steal the original video.

Jiro has avenged the murder of his mentor and stands alone as an assassin. He finds a new agent and makes a contract with him. However, the ghost of someone whom he once killed, appears...

Downtown Los Angeles. It is a shadowy town filled with drug addicts, homeless people, and others who have lost their homes. Jiro, tired of his killing spree, is also addicted to drugs and drifts through his days like a corpse. Jiro's foggy mind begins to flash with blood-soaked reminiscences...

In the middle of the desert, a solipsistic Japanese-American woman, along with her elderly and paralysed friend Barbara, runs the Desert Rose Cafe. Things liven up with the arrival of a mafia henchman (whose boss is hiding out at a nearby ranch), a battered Japanse man (who turns out to be a terrific chef, but who also triggers Barbara's memories of internment during WWII), and an attack on the mob boss' camp.
