Prehistoric sea-giant rages against city!

Near the Arctic Circle researchers detonate a nuclear device and unwittingly thaw a prehistoric beast frozen for millions of years. The monster leaves a path of destruction across eastern North America as it heads straight for New York City.

Stone (Lee Van Cleef) will deliver it by grenade.
