For the scientist, Dr. Karl Sorenson (William Devane) is about the only person on Earth who believes that the runaway asteroid won’t miss our planet by several million miles, and nobody will believe him, so he’s commandeered the missiles to use them to destroy the asteroid. How does he know? From cave paintings by an ancient tribe of Australian aborigines, who have already predicted events including the Irish famine. Sorenson, you see, is an astronomer and anthropologist. But the secretary of defense sees him as a terrorist, and is on the verge of bombing the silo and everyone in it.
To the rescue comes Our Heroine, Sorenson’s long-estranged daughter, Katherine (Connie Sellecca). Can she — will she? — convince her father to give himself up? And keep in mind that the “terrorists” aren’t too bright: In what may be many viewers’ favorite scenes, one confronts a small team of soldiers manning the silo and asks, “Which one of you is Gibson?” and is totally perplexed when none of the soldiers will reveal their comrade — until he (Roger Cross) steps forward, with the name Gibson right where it should be, above his uniform shirt pocket.
Still, a couple of plot twists in Donald Paul Pemrick and Dean E. Fronk’s script keep the film relatively interesting under Brian Trenchard-Smith’s taut direction. Devane almost manages to keep a straight face, and Marsha Warfield shows a strong presence as an FBI agent.
