In this new volume, Lucky Luke has to clean out a whole city: Fenton Town, so named because, after being abandoned by the pioneers who founded it, it has been taken over by Dean Fenton, a desperado of the worst sort... Fenton Town has become the most depraved city in all of Texas. Lucky Luke makes a short visit to town—just the time needed to put Fenton in prison and chase out the remaining rabble.
But soon the Dalton Brothers take up the torch, and, following Fenton’s ideas, create... Dalton City, exclusively reserved for gangsters!!! They even capture Lucky Luke and force him to help them...
