A group of secretive scientists develop time travel near Idaho’s Craters of the Moon,
discovering a near-future apocalypse. Since anyone much over age 20 can’t survive
traveling, they’re in the process of sending a group of young people, including Isa and her
withdrawn sister Karen, beyond the apocalypse to rebuild civilization. Things go wrong (not
the least of which are the plot, the dialogue, the acting, the sound track, and the
requirement that the young Jane Fonda lookalikes must strip to travel through time), but even
so, the film has a certain unprepossessing appeal.

You see, Dad and Lewis are trying to get it together, to secretly transfer a lot of young
people into the future, bypassing the eco-crisis or whatever it is. Start a new
civilization.
