A solid and generic piece of blaxploitation. Yaphet Kotto completism. He's a lot better than the material; IMDB trivia says he only took the gig because he was getting divorced. Isaac Hayes lead and did the soundtrack, clearly aiming to recapture the success of Shaft and seed a franchise. Nichelle Nichols plays a madam with a vast wardrobe in her one-and-only jaunt into the genre.
I can't say I understood the plot too well which was perhaps because there isn't much of one. Hayes and partner Alan Weeks are "skip tracers", i.e., bounty hunters for a bond bailsman in Los Angeles. One pimp puts up a bit too much of a fight so Nicols takes umbrage and puts out an "insurance" contract on Hayes. Kotto is somehow a big cheese in the killing-for-money game despite his employees being dispatchable with ease. In between the action Hayes gets to squeeze Annazette Chase who is a sincere cat fancier; Ginger Frances put in a solid shift before being used to inflame the situation. The scenes where she gets out of the joint are very funny.
