Dr William Shatner investigates when a number of animals start dying of spider bites. Huge spider hills appear and soon the Shat is up to his neck in arachnids as they turn to killing the population of the town.
This is great fun and I was actually very impressed by the sheer amount of Tarantula on screen and on the actors. Not a fake spider in sight as the Shat and friends board up a diner and try to fend off the invading army.
