Australian sheep-man Morgan Lane comes to Montana looking for government-owned grazing land, and encamps his sheep at the boundary line (where the bad grazing ends and the good grazing begins) set up by the cattle barons to keep the sheep from nubbing away at the good grass. He goes to town, posing as a merchant, explains his Australian accent, and learns that Maria Singleton, owner of a large ranch, and Rodney Ackroyd (who never explains where he got his name), another ranch owner and Miss Singleton's fiancée, are the leaders of the cattlemen against the sheep-men. Romance tugs at Morgan and Miss Singleton, who quickly decides that Morgan has a much better name than Rodney (and other attributes) but the cattle-vs.-sheep feud keeps them apart. Until they meet in the street for a showdown gunfight following a disastrous clash between the cattle and sheep factions.

British hunter Thorndike vacationing in Bavaria has Hitler in his gunsight. He is captured, beaten, left for dead, and escapes back to London where he is hounded by German agents and aided by a young woman.
