The time is the tomorrow after tomorrow and mankind has now populated the Moon where vast domed cities have been built on what was once a wasteland. But when the power-mad Emperor Omus (Oscar winner Jack Palance of CITY SLICKERS) attacks the lunar colony of New Washington, a team of scientists led by Dr. John Caball (Barry Morse of SPACE: 1999) launches a dangerous mission to destroy the dictator and his robot army. Can three daring space jockeys and one renegade robot save their universe from the dark forces of intergalactic evil?
