Kenneth More portrays a British gunsmith who travels to the American West. After winning a rigged poker game, More is appointed sheriff of Fractured Jaw, a wide-open town where law officers are plugged and planted on a regular basis. He befriends hard-bitten saloon gal Jayne Mansfield, who doesn't give the gentlemanly More much chance of survival. Using his wits, and blessed with a generous amount of raw luck, Sheriff More escapes death at every turn, finally becoming the "blood brother" of a previous hostile Sioux tribe. With the help of his Native American friends, More brings law and order to Fractured Jaw. The film's main advantages are Kenneth More, who is superb as always, and Jayne Mansfield, giving one of her best and least mannered performances.
