The idea of the show was that a person who had suffered an injustice that had gone unpunished would receive an anonymous note offering 'Vengence Unlimited'. They would then receive a visit from Mr Chapel, who would offer to help them get justice in exchange for either One million dollars, or, somewhere down the line, a single favour. Of course, none of the victims could afford that, so this left a very good trail of people in varying positions and authority to help right other people's wrongs later in the show.
The first episode followed a quest to set up the murderer of a mother, who was freed by a corrupt lawyer. Kathleen York's character was introduced as just another person who owes Chapel a favour for, Unlike the other people he had helped though, at the end of the first episode she tracked him down help him help others.
This was a good vehicle for Michael Madson, as he got to play his usual cool likable rogue but as a good guy, so not someone to be killed off at the end! The plots were intelligent, and it was always fun to try and work out how he would finally the bad guy. Another one to chalk up on the 'why did they cancel this?!' list.
