Prisoners of the Lost Universe

An earthquake hits just as a scientist runs his matter transmitter, and three people are thrown into a parallel universe. Carrie Madison (Kay Lenz) and Dan (Richard Hatch) land in Vonya, a world ruled by the warlord Kleel (John Saxon), where they have only modern technology and medieval weapons to save the people. Terry Marcel shot it in South Africa, and Dan stands there in the open country, a sword in his hand.
