John Casey is a man on a mission to rescue his beloved wife, Mary, from the clutches of Maximiliano Cabal, a notorious Mexican bandit ravaging California's border towns and stealing cattle. The only way to secure Mary's release is to barter with Cabal, offering up to fifty Winchesters in exchange.

With the help of his trusted companion, Bear Claws, John sets out on a perilous journey to retrieve the rifles and reclaim his wife. But as the two men cross into Mexican territory, they quickly find themselves double-crossed and on the run from Cabal's men.

As they navigate the dangerous landscape, their only reliable ally is an Apache warrior joining them in their fight against Cabal and his men. With bullets flying and the odds stacked against them, John and Bear Claws must use all their skills and cunning to survive and rescue Mary from Cabal's clutches.
