Commander Koenig (Martin Landau) and the crew of Moonbase Alpha find themselves facing off against the maniacal alien Mentor (Brian Blessed), whose daughter, Maya (Catherine Schell) is endowed with the ability to transform herself into any life form. Mentor plots to drain the minds of the Alphans, while Koenig attempts to extricate them from the situation.
In the second half, Dr. Helena Russell (Barbara Bain) tries to treat Maya, who has contracted a disease that causes her to lose control of her transformations. Meanwhile, Koenig and pilot Alan Carter (Nick Tate) are trapped millions of miles away from Alpha on the other side of a space warp.
Segment Three: The Bots help Joel with his taxes. It goes pretty well until Crow and Servo discover they're being claimed as "business expenses." Crow: "Maybe we should be wearing ties and demanding maintenance contracts!"
Segment Four: The crew of the SOL play a game of football, and Gypsy and Joel duet on "We Are the Champions". The whole thing degenerates into a tickle fight as the credits roll. (A portion of this scene was included on the MST3K Scrapbook tape.)
- "Super Bowl Sunday"
- This episode aired on January 22, 1989, the same day as Super Bowl XXIII. The mads are wearing the "no-d" glasses because the half-time show that year was in 3-D.
- When the ITC (Incorporated Television Company) logo appears at the beginning of the movie, Tom asks if that logo reminds them of The Muppet Show. Both Space: 1999 and the Muppet Show were produced by ITC, a well-known television company in the UK, founded by Lord Lew Grade.
