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!"
