Death Wish 4: The Crackdown

Roughly one year after the events of the previous film, Paul Kersey is back in Los Angeles and is living a quiet life as an architect at his own firm, haunted by nightmares of his past as a vigilante. Erica, the teenage daughter of Karen Sheldon, Paul's current girlfriend, goes with her boyfriend, Randy, to an arcade to meet up with a man named JoJo Ross. JoJo offers her crack cocaine, and Erica dies from an overdose. Having seen Erica smoke a joint with Randy while in his car the previous night, Paul suspects Randy was involved with Erica's death, so he follows him to the arcade. Randy confronts JoJo, only to be killed by him before Paul shoots and kills him. At home, Paul receives a package indicating the sender knows he's "the vigilante," and a phone call threatening to go to the police if Paul won't meet. Paul is taken to the mansion of the secretive tabloid publisher Nathan White. White says that his daughter became addicted to drugs and eventually died of an overdose, so he wants to hire Paul to wipe out the drug trade in Los Angeles. There are two major gangs competing for the local drug supply: one led by Ed Zacharias, the other by brothers Jack and Tony Romero. Kersey accepts and White supplies him with weapons and information. Meanwhile, LA detectives Sid Reiner and Phil Nozaki investigate the arcade deaths.
