Coffy is a nurse whose younger sister gets involved in drugs and is severely injured by contaminated heroin. Coffy sets out on a mission of vengeance and vigilante justice, killing drug dealers, pimps, and mobsters who cross her path.

Coffy, a beautiful young nurse, is determined to get revenge on the people responsible for turning her sister into a drug addict. She poses as a prostitute, exploring the world of gangsters, pushers, pimps and crooked cops, searching out and ultimately murdering the guilty scum.

Pam Grier stars in the grindhouse favorite directed by Jack Hill, as a nurse bent on vengeance when her younger sister becomes an addict.

Writer-director Jack Hill (Spider Baby, Switchblade Sisters) managed to beat Death Wish to the screens by a year with this violent tale of a citizen touched by crime and deciding to fight back. Her little 11-year old sister is a hopeless addict, the police can't help, and poor Nurse Coffy Coffin (Pam Grier) has no choice but to take the law into her own hands. Posing as a Jamaican prostitute, Coffy infiltrates the lairs of pimp King George (Robert DoQui) and kingpin pusher Vitroni (Allan Arbus). Eventually, after her childhood sweetheart is beaten into a coma and she finds out her politician-lover (Booker Bradshaw) is involved, Coffy kills everyone with a shotgun. However, by having a black woman named Coffy get injected with a sugar mixture (the crooks think it's heroin), one can only imagine the filmmakers cackling about Coffy with cream and sugar. In fact, the original ad line promised Coffy...she'll cream you! ~ Robert Firsching, All Movie Guide.
