Cold and arid, Mars is the perfect test of humanity’s mettle against the elements. After three generations, life on the Martian frontier is still raw and marginal. The lifeblood of this new world is laid down in the form of mighty rail lines. Jefferson Brodie believes extending the maglev rails south to the polar cap would alleviate most of the hardships by bringing needed water and ice to the settlers; an expansion plan that places the unregulated settlements on thin ice with authorities on Earth. Life gets complicated when a nosy reporter from Earth shows up along with the Regional Planetary Environment Control breathing down his neck to halt the rail construction, threatening not only Brodie’s dream, but the settlers’ very survival. Vindictive anger brings destruction into the already fragile web that holds the Mars colonies together. Two extremes do their best to end efforts for a free life through demolition and bureaucracy while those close to the center are forced to re-evaluate what they believed to be right. Curiosity leads to doubt and then fear of discovery as ideals are traded underneath new skies. Redline brings the old west frontier onto the surface of Mars in an effort to recapture the age old search for freedom to think, live, and breathe clean air. Facing an impossible task in surmounting fear and clashing micro-cultures, enjoy the blending of views and lives that start in separate worlds and must ultimately blend together or be forever lost.
