Idaho Transfer

Teenager Karen Braden (Kelley Bohanon) is a troubled mental hospital outpatient who is taken by her father George and sister Isa to a government facility near the Craters of the Moon lava fields in Idaho. The project there was commissioned to develop matter transference, but made a different discovery: time travel. The time travel process has negative health effects, though. Adults "not much older than 20" are unable to survive for long, as their kidneys hemorrhage shortly after the experience.
