Cosmic Princess is comprised of scenes from the syndicated TV series Space 1999. Most of this "TV movie" consists of the series' second-season opener, which introduced Maya (
Catherine Schell), an extraterrestrial endowed with the ability to transform herself into any life form. Maya is the daughter of Mentor, an evil alien who tries to drain the minds of the Moonbase Alpha crew. Befriending the Earthlings (among them series regulars
Martin Landau,
Barbara Bain and
Barry Morse), Maya helps them escape Mentor's clutches. ~ Hal Erickson, All Movie Guide
