A sports physician, inspired by his knowledge that a potentially fatal cerebral condition could be hereditary and motivated by the tragic death of his father to the same condition, convinces his younger brother to undertake a rigorous bicycle training regimen with him. Despite the younger brother's initial reluctance, swayed by concerns for his own health and a desire to break free from the shadow of a perceived family curse, he eventually agrees. Their training is not just about physical endurance but also about mending the strained relationship they have endured for years, resulting from a family secret that tore them apart. As they push their limits on the bike, they start to reconnect, finding common ground and mutual respect through their shared challenges and aspirations.

Together, they set out to compete in a grueling bicycle race across the Rocky Mountains known as "The Hell of the West." This challenging competition is not only a test of their physical limits but also an opportunity to prove to themselves and each other that they can overcome the shadows of their past. As they embark on this intense journey, fraught with competitive rivalries, physical hardships, and personal demons, the brothers encounter a cast of colorful characters who enrich their experience. These encounters and the challenges of the race serve to deepen their bond, teaching them about the value of perseverance, teamwork, and the unwavering strength of family ties.
