The Black Scorpion

The Black Scorpion is horror with a sting more lethal than the king-sized ants that overran Los Angeles's sewers in the classic Them! Can humankind survive these invincible juggernauts? That fate rests on the shoulders of Hank Scott as the creatures rip a train from its tracks, snatch a helicopter from the sky and, in the film's most gripping sequence, battle each other in their subterranean lair. Watch out! (official distributor synopsis)
