Massacre Canyon plot
"THUNDERING Out Of The Reservation! THE LAST ATTACK OF THE APACHE NATION!"
Inexperienced cavalry lieutenant and heavy drinker Richard Arlington Faraday and his platoon must lead a caravan of Henry repeating rifles and the attractive ladies Flaxy and Cora through enemy territory of the Apaches. Indian expert Sergeant James Marlowe is also part of the escort. Marlowe's promotion is blocked by the arrival of the young officer Faraday. The soldiers are dressed as civilians and Flaxy and Cora have joined the caravan on the way. Due to an army blunder, Chief Running Horse gets information about this secret weapons transport through his territory. Running Horse wants to trap the caravan in 'Massacre Canyon'. In addition to the threat of the Apaches, the cavalrymen and both ladies also have to deal with the difference of insight and approach between Faraday and Marlowe.
