Beast from Haunted Cave

A group of bank robbers, led by ruthless Alexander Ward (Frank Wolff), hatch a plan to steal gold bars from a vault in Deadwood, South Dakota. As part of their heist, Marty Jones (Richard Sinatra) plants a time bomb in a nearby gold mine. The detonation will act as a diversion for their robbery. Led by Gil Jackson (Michael Forest), the gang succeeds in stealing the gold bars, but their journey is soon disrupted by a giant spider-like monster that feeds on human blood, having previously captured and killed several people, including local barmaid Natalie, who becomes Gil's love interest. Gil, accompanied by Gypsy (Sheila Noonan) - Alexander's secretary - takes shelter in an abandoned mine cave where they initially escape the beast. However, their refuge turns out to be the monster's lair, leading to a violent confrontation that ultimately results in the death of the gang members and the destruction of the creature with a flare gun shot by Marty Jones.
