Coffy

Nurse "Coffy" Coffin (Pam Grier) seeks revenge for her younger sister's getting hooked on drugs and having to live in a rehabilitation home, a product of the drug underworld, mob bosses, and a chain of violence that exists in her city. The film opens with Coffy showing her vigilante nature by killing a drug supplier and dealer. She does this without getting caught by using her sexuality as an attractive and athletic woman willing to do anything for a drug fix.
She lures the men to their residence, which gives her the privacy to kill both. After the killings, Coffy returns to her job at a local hospital operating room, but is asked to leave when she is too jumpy when handing tools to the surgeon.
The film introduces Coffyâs police friend Carter (William Elliott), who used to date Coffy in their younger years. Carter is portrayed as a straight-shooting officer who is not willing to bend the law for the mob or thugs who have been bribing many officers at his precinct. Coffy doesn't believe his strong moral resolve until two hooded men break into Carter's house while she's there and beat Carter severely, temporarily crippling him. This enrages Coffy, giving her further provocation to continue her work as a vigilante, killing those responsible for harming Carter and her sister.
Coffy's boyfriend Howard Brunswick (Booker Bradshaw) is a city councilman who appears to be deeply in love with Coffy at the beginning of the film. Coffy admires Brunswick for his body as well as his use of law to solve societal problems. She is very happy when he announces his plan to run for Congress, and his purchase of a night club. The two share a passionate love scene in the first part of the film.
Coffy's next targets are a pimp named King George (Robert DoQui), who is supposedly one of the largest providers of prostitutes and illegal substances in the city, and Mafia boss Arturo Vitroni (Allan Arbus).
Coffy questions and abuses a former patient of hers who was a known drug user to gain insight into the type of woman King George likes and where he keeps his stash of drugs. This is the first scene where Coffy brutalizes another woman and shows no remorse because the former patient is using drugs again and thus a societal deviant. Coffy quickly goes to a resort posing as a Jamaican woman looking to work for King George.
George is quickly interested in her exotic nature and asks her to come with him back to his house to experience Coffy himself first. One of the prostitutes returns from a far away job and gets disgruntled and jealous when seeing George taking such a liking to Coffy. At a party later that day Coffy and the other prostitutes get into a massive brawl, which entices mob boss Vitroni and he demands that he have her tonight.
Coffy prepares herself to murder Vitroni and just when she is about to shoot, is overtaken by his men. She lies and tells Vitroni that King George ordered her to kill him, which makes Vitroni order George to be murdered. Vitroni's men kill George by dragging him through the streets by a noose.
Coffy then discovers her clean-cut boyfriend is actually corrupt when she's shown to him at a meeting of the mob and several police officials. He denies knowing her other than as a prostitute and Coffy is sent to her death. Once again, Coffy uses her sexuality to seduce her would-be killers. They try injecting her with drugs to sedate her, but she had switched these out for sugar earlier. Faking a high, she kills her unsuspecting hitmen with a pointed metal wire she fashioned herself and hid in her hair.
Running to avoid capture, Coffy carjacks a vehicle to escape. Coffy drives to Vitroni's house, murders him, and then goes to Brunswick's to do the same. He pleads for forgiveness and just as she is about to accept, a naked white woman comes out of the bedroom. At this, Coffy shoots Brunswick in the groin. The film then closes with Coffy being satisfied at having avenged her sister and Carter.
