With the help of his team, called the Hong Kong Cavaliers, Banzai has just stumbled upon a great discovery. A device called the oscillation overthruster has just been perfected, allowing man to venture into another dimension right here on Earth. His discovery was a long time coming. His mentor, Dr. Hikita (Robert Ito), first built the prototype back in 1938. Hikita’s partner, Dr. Lizardo (John Lithgow), became stuck between dimensions all those years ago and is now currently living in a mental home where his brain is also occupied by a member of the evil alien race, the Red Lectroids, who are currently living in this other dimension and trying to break free and return home. I think.
The plot is pretty convoluted and much of the crucial information is given during a two minute hologram message, a la Princess Leia, where a member of a rival alien race, the Black Lectroids, tries to explain what’s going on.
