SLAUGHTER'S BIG RIP-OFF

Slaughter (Jim Brown), a fierce Vietnam veteran and ex-Green Beret, had avenged the death of his parents by killing in Mexico the gangster responsible. He is now relocated in Los Angeles, California, where Slaughter sought to escape the past and try to have a tranquil life.

Slaughter goes to a friend's house for a lavish outdoor picnic and celebration. Meanwhile, a new crime boss, Duncan (Ed McMahon), is now after Slaughter, for having killed ex-Mafia boss Dominic Hoffo earlier. An old World War I biplane is seen flying by the outdoor celebration and then opening fire on the guests at the picnic. It results in the graphic death by headshot of Slaughter's friend, which reignites the old spark of fury and rage that Slaughter had when told of the death of his parents.

Duncan's first assassination attempt in essence is a failure and only succeeds in waking a sleeping beast. Duncan hires a new hit-man named Kirk (Don Stroud) to bring Slaughter to his demise. Rather than being in protective custody under the supervision of Duncan's crooked cops, Slaughter remains on the streets.

Slaughter's new friend is a police official, Det. Reynolds, who warns that his life is in peril. Slaughter also has a girlfriend, Marcia (Gloria Hendry), who is also being targeted by the mob, under Duncan's orders, to further provoke Slaughter.

Slaughter makes an agreement with Reynolds to obtain confidential documents of the Mafia's operations. He coaxes a drug-addicted pimp to assist him in breaking into Duncan's safe house and successfully escape with the documents. After gun fights, Slaughter and his pimp sidekick kill several of Duncan's guards and associates. In response, Duncan sends Kirk to kidnap Slaughter's girlfriend, a fatal mistake on Duncan's part.

Slaughter and his pimp accomplice infiltrate Duncan's safe house, kill several of Duncan's men during an armed confrontation, and successfully obtain confidential Mafia documents. Duncan's attempt to kidnap Slaughter's girlfriend leads to further violence.

The film concludes with Slaughter decisively dismantling Duncan's criminal operation through force and cunning, reclaiming agency after repeated attacks on himself and his loved ones. The ending underscores the blaxploitation ethos: the protagonist overcomes systemic corruption and personal vendetta through relentless, righteous violence. The resolution both satisfies the revenge narrative and cements Slaughter’s status as an unstoppable antihero.
