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…
