A white Detroit detective (Alex Rocco) has to investigate a heist at a political fundraiser and he's none too happy about it. He's even less happy when he's forced to partner up with a black detective (Hari Rhodes). Despite their differences, the two cops work well together and get to the bottom of things.
Alex Rocco and Hari Rhodes are both good. Beautiful Vonetta McGee isn't on screen nearly enough but has an important part. The minor roles are played by a variety of actors, some of whom seem like complete amateurs who recite their lines robotically. The actress playing Rocco's wife has one scene and she uses it to give a lesson on terrible acting.
Mostly straight but there are some unintentional moments of hilarity. Such as a car moving at slow speed driving into a parked car, causing both vehicles to instantly explode like they were packed with dynamite. Or an older white reporter seriously asking the Chief of Police "Do you think it was a honky caper?" There's also a scene that rips off Dirty Harry's "do you feel lucky punk" scene. The dialogue is different but the scene is too similar to be a coincidence considering Dirty Harry came out a couple years before this and that scene was an instant classic.
It's a good blaxploitation flick. I enjoyed all of the Detroit locations, including many now-demolished buildings. It's obviously a limited movie, in terms of budget, but it's still entertaining.
