Alone in the Night on AllMovie

This Japanese action film offers Westerners a look into the seamy world of the Japanese Mafia (the yakuza). Nami loved her husband, a policeman with an undercover assignment to get into a yakuza gang of drug-dealers. The ruse failed and he was shot to death and dumped into the sea. While Nami was mourning, the drug dealers broke into her home looking for confiscated amphetamines. They then raped her and broke her husband's funeral urn. Traumatized, Nami attempts suicide but is rescued by the mysterious and heavily tattooed yakuza, Muraki. She decides to seek revenge and so pretends to be a prostitute in order to get close to yukaza ring leader Ikejima. She succeeds, but then fails in her attempt to murder the crime lord. Once again she is saved by Muraki. She is sold to a brothel where she becomes a drug addict. Muraki again intervenes and she is able to kick the drugs and return to her quest for revenge.
