Boss rider "Careless" Carmody (William S. Hart) is made sheriff of an Arizona frontier town by Chicago swindler Prentice (Bert Sprotte). The naive Carmody actually believes Prentice to be on the up and up and vouches for him in a land deal with Ruth Fellowes (Seena Owen). Taken to the cleaners, so to speak, Ruth blames Carmody, who, in love with the girl, follows Prentice back to Chicago. Rounding up Prentice's enemies among the cow men at the stockyards, "Careless" finally gets the goods on the swindler. Not one of Hart's better vehicles, Breed of Men, in the words of critic Louis Reeves Harrison, "lacked that essential element of drama -- suspense."
