Beast from Haunted Cave

A group of criminals hatch a plan to steal gold bars from a bank vault in Deadwood, South Dakota. They set off to a remote cabin, where they hope to be picked up by a plane. But a violent snowstorm forces them to take shelter in a cave, which turns out to be the lair of a beast. The beast kills the remaining gang members, but Marty shoots it with a flare gun before dying.
