The Metaliens, alien robots intent on galactic domination, encounter a major setback. Their enormous Space Saucer, 'Compromise', enters a black hole in a strange, uncharted region of Space, and collides with another craft – sending the Kleptonite Ball, their precious cargo and the key to Universal Conquest, hurtling to a planet inhabited by primitive life forms: Earth. Having materialised in a bar, the Ball variously functions as a Christmas tree decoration, a bathroom ornament, and a fortune-teller's prop. The Metaliens must retrieve the Kleptonite Ball if their mission is ever to succeed. And that's when their problems really begin…
Unfortunately the movie Stainless Steel and the Star Spies is not yet available on HBO Max.
