"The Fourth Durango" is not your ordinary Durango. It's not in Spain, or Mexico, and it's not a ski town in the Colorado Rockies, although Durangos do exist in all of those places. This Durango has an industry, albeit a rather odd one: it is a hideout business, a place where people pay to find sanctuary from former friends and associates who are either trying to kill them, or have them killed. Into this Durango comes a former chief justice of a state supreme court, followed by son-in-law Kelly Vines to act as his emissary to the beautiful and savvy mayor. Following them come a false priest, and a run of murders.
