Coffy is a 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. But what Coffy doesn't realise is that all is not what it seems - and that the leafy green behind the pushers' scene just may come from someone she knows.
