This feature-length sci-fi offering is a spin-off of a popular cartoon from Japanese television. In this installment, Kain, a powerful alien being, escapes from the prison of the Galactic Police. In a familiar plot device owing heavily to the time-travel conventions from The Terminator and Back to the Future, Kain transports himself back in time to kill Tenchis mother to prevent the birth of Tenchi, who saved the universe in the original series. Tenchi, fading from existence, must travel with his friends back to 1970 to save his mother. The soundtrack features a song performed by German New Wave musician Nina Hagen. ~ Jonathan E.
