O'Rourke (Forrest Tucker) loans the fort's only cannon to the Hekawi Indians who want to use it for a tribal festival. Unfortunately, the cannon "disappears" at the precise moment when Captain Parmenter (Ken Berry) must impress a visiting colonel (played by former B-western hero Don "Red" Barry). Now it is up to O'Rourke and Agarn (Larry Storch) to get the cannon back without ruffling the feathers of their pal and business partner, Chief Wild Eagle (Frank DeKova). Don Diamond makes his first series appearance as Crazy Cat (though he's not so named on-screen). ~ Hal Erickson, Rovi
