The science fiction film begins when astronomer Zane Zaminski receives a signal from a distant star, who reports and presents all evidence to his boss, Phil Gordian, and is expelled immediately. Hagen becomes obsessed with identifying signals again and finds a transition to outer space in the same wave of Mexico, flying to the place. In the meantime, scientist Ilana Greene is investigating the unjustifiable increase in temperature in Third World countries and is going to Mexico for further research.
A movie that shoehorns a blunt warning into its silly but entertaining story of a young radio astronomer's one-man battle against sinister extraterrestrials.
