It's 1983, and Tony Montana is raking in millions of dollars as the biggest drug lord in South Florida. Meanwhile, Paul Kersey is in Miami visiting his retired aunt, Edna, a year after the events of Death Wish 2. But -- wouldn't you know it? -- while she's out shopping one day, Edna is fatally gunned down during a shootout between some of Montana's thugs and rival gang members.
Never one to forgive and forget, Kersey decks himself out all in black, arms himself with an Uzi submachine gun, plenty of spare clips and two hand grenades, and infiltrates the grounds of Montana's estate late one night, planning to mete out his usual brand of vigilante justice. As luck would have it, Montana's men are all partying down at the Babylon Club, and the gate and front door have been left open.
Montana is up in his office snorting coke off his desk, when he spots Kersey approaching the front door on his CCTV display. Assuming it's an assassin sent by the Diaz brothers, he grabs his grenade launcher-equipped assault rifle, plenty of spare clips and a second grenade, and issues a stream of profanity-laden trash-talk, psyching himself up for the battle to come.
The stage is set. The safety catches are decidedly off. Who, if anyone, comes out of this alive?
