Hellgate on AllMovie

This western stars Sterling Hayden as a man who innocently tends to the needs of a mysterious stranger. When it turns out that the stranger was part of a notorious gang of mercenaries, Hayden is condemned as a conspirator and sent to Hellgate Prison in New Mexico. He earns a pardon thanks to his courage and medical expertise during an epidemic. Hellgate was one of a handful of ambitious 1950s projects from the otherwise cost-conscious Lippert Studios.
