James Coburn plays Jess Newton, a knife throwing bully who hates foreigners.
It just so happens that Gino Pelleti (Danny Thomas) and his son George (Nick Adams) are Italian immigrants who arrived to this small frontier town from California.
They plan to open a tailor's shop but Jess Newton and his cronies plan to drive them out. The Pelleti's are mocked and made fun off. Their shop is ransacked.
Gino wants to turn the other cheek. He does not want to get into a scrap but George does. Jess decides to take George out for a drink for standing up to him. The implication being that he will later get revenge on him.
Gino challenges Jess to a duel as he does not want his son hanging around with Jess. It will lead to more trouble.
Jess wants to get into a gunfight with Gino but the wily old tailor has his own weapons to draw on.
It seemed the story was George would get stitched up by Jess and his gang. So it was a surprise that did not happen. It would have been a better motivation for Gino to challenge Jess.
