Breakheart Pass / Valdez Is Coming (Double Feature)
In 1870, the soldiers of an army outpost in Utah are supposedly suffering from a diphtheria epidemic. Fortunately, a train filled with additional soldiers, medical supplies and a motley crew of passengers is on its way. One traveler is John Deakin, an undercover agent posing as an arrested criminal. When Deakin begins snooping around, he makes a stunning discovery that there is no epidemic at the fort. The lie is actually part of a conspiracy between a group of killers and a tribe of Indians who plan to take over the outpost and steal its gold and silver. Can Deakin foil the plan before it's too late?
Valdez Is Coming
After shooting a wrongfully accused man during a tense stand-off, constable Bob Valdez realizes the fugitive's pregnant Indian girlfriend has been left without anyone to support her, so he decides to ask everyone involved in the shootout to put together $100 for the squaw. However, this doesn't please Tanner, the posse's ill-tempered leader who publicly ridicules Valdez, and has him severely beaten by his goons. The quiet and unassuming Valdez retreats just long enough to recuperate, and when he returns, he goes after Tanner with a bloody vengeance.
