Dennis Quaid, Michael Chilkis and co will not be coming back for a second series so you may as well say your goodbyes to Vegas this evening. Sheriff Lamb and Savino have had enough of Porter Gainsley: His bombing of the tumbleweed and attempt on Katherine's life were enough to bring the enemies together, with a plan to errr, take care of him at a livestock auction. Of course, these things never go to plan, so when Dixon shows up with a weapon of his own, all hell breaks loose.
