Claude Lacombe (Francois Truffaut) is investigating mysterious happenings around the globe including the appearance of aircraft lost in 1945... fully fuelled and operational.
Meanwhile electrical lineman Roy (Richard Dreyfuss) has a mysterious encounter of his own when strange lights overhead give him sunburn. Jillian (Melinda Dillon) suffers shock when her house is blasted by strange lights and her son goes missing...
Both Roy and Jillian have a compulsion and an obsession with a mountain in Wyoming. This just happens to be where the US military has launched a mass evacuation. What is at that mountain. Roy and Jillian go and find out. What they find exceeds anyone's expectations.
Although the film does sometimes drop into farce it is a wonderful experience visually. For a change the aliens arn't evil and the US military intent on shooting everything which moves.
