Storyline
J.J. (Rod Perry) is a hustler with a conscience.

After a violent confrontation with mobster Tony Burton (Don Chastain) leaves a friend dead, J.J. becomes the ally of local numbers king Nate Williams (Jimmy Witherspoon), who teaches him how to dismantle Burton's drug operation brick by brick. But Burton has a secret weapon: Detective Jo Sterling (Duncan McLeod), a crooked cop who's got dirt on all the syndicates, is now Burton's lap dog.
