When their train is hijacked, two railroad detectives take to the prairie
On the Colorado railroad, two men enforce the law: a hired gun named Tango and a smoothly dressed sleuth named Ned Chambers. As they pass through the frozen landscape on their way to Denver, Ned watches two well-heeled guests: the aristocratic beauty Lady Marina Simpson and Adam Wilson, the vice president’s brother, who has come to assess the territory’s readiness for statehood. When a bonfire on the tracks stops the train, Tango and Chambers hustle their VIPs out into the night. The wilderness is dangerous, but to stay behind means certain death.
Hijacked by bandits, the train pulls away without the small party, abandoning them on the frozen prairie. Tango and Chambers have only one chance to reach Denver alive: They must make like outlaws and steal back their train.
