Frontier Horizon - Originally called New Frontier the film was re-titled Frontier Horizon to avoid confusion with a 1935 John Wayne/ Republic release called The New Frontier. Frontier Horizon is the 8th of a series of The Mesquiteers releases by Republic starring Wayne, Ray Corrigan and Raymond Hatton.
It is not so much a western as a drama with a western theme: eminent domain is being used to damn off a valley and the town therein to make a reservoir to provide water for a larger city. Unfortunately, the problem is compounded by a crooked politician, real estate man and damn construction crew boss. They offer to move the townspeople to a new location which will be watered by a pipeline - only the pipeline was just a story based on a small show of construction and good faith on both sides. Can the Mesquiteers sort things out - watch and see.
