In her first top-billed role, “The Queen on Blaxploitation” Pam Grier is Coffy; nurse by day and avenging angel by night. When she discovers that her little sister has been doped up — and freaked out — by a greedy drug pusher, she not only puts an end to his miserable days, but she vows to follow his trail of corruption up to the top — the very top. But what Coffy doesn’t realize is that all is not as it seems — and that the leafy green behind the pusher’s scene just may come from someone she knows. A transformative romp that sent Grier’s career into the stratosphere, Coffy is a pulpy masterpiece that flipped the Blaxploitation genre on its head.
