Director Monte Hellman (who would later direct a young Jack Nicholson on two low-budget westerns) earned his low-budget wings on Filmgroup's bizarre fusion of hostage/crime thriller and big-rubber-monster flick -- a quirky juxtaposition employed to similar effect 35 years later in From Dusk Till Dawn. The story begins with a team of gold thieves hiding out in a ski resort cabin after a heist, taking two people hostage as they prepare to smuggle their loot across the Canadian border -- unaware of the giant, icky-looking spider-monster lurking in a nearby cave, which preys on anyone unlucky enough to stumble near its lair. The film's woodland exteriors add a richness lacking in the typical dusty desert settings of this film's genre contemporaries. The cobwebby monster is played by Chris Robinson, later the star of General Hospital.
