In the distant future, humanity has colonized the stars. To maintain peace and order across mankind's New Frontier, Earth's Cavalry Command develops the "Ramrod Equalizer Unit", a transforming battleship operated by their elite unit of special operatives, the Star Sheriffs, to defend the settlers of the galaxy. Their biggest threat? The Outriders, a group of extra-dimensional beings that intend to conquer our dimension and enslave humanity with their superior technology and weaponry. Armed with their wits, courage, and of course, Ramrod, it's up to Saber Rider and his team to stop the Outriders once and for all and bring peace to the universe!
