Filmed in South Dakota at the same time as Ski Troop Attack, it tells the story of bank robbers fleeing in the snow who run afoul of a giant spider-like monster that feeds on humans.

Plot
A group of criminals, led by the ruthless Alexander Ward, hatch a plan to steal gold bars from a bank vault in Deadwood, South Dakota. Ward sends one of his henchmen, Marty Jones, to set an explosion in a nearby gold mine; the detonation will act as a diversion for their heist. Although Marty, accompanied by local barmaid Natalie, succeeds in setting off the explosion, he encounters a beast in the mine. The beast kills Natalie, but Marty escapes with his life.
The next morning, the explosive goes off as planned, and Marty and his gang succeed in stealing gold bars from the vault. Led by a local guide named Gil Jackson, they set off to a remote cabin, where they hope to be picked up by a plane. Gil is initially unaware of their plans, but he becomes suspicious when he hears reports of the robbery on the radio and discovers that they're carrying handguns. They reach the cabin without incident but, once there, a violent snowstorm delays the plane's arrival. Marty's "secretary" Gypsy is taken with the young Gil and tells him that Marty plans to kill him once the plane arrives. Gil and Gypsy take off back to town together.
