Impresario J. C. Tenpecent had invented an uncanny magician robot billed as MISTER ABRA KADABRA. Not content with presenting KADABRA as a theatrical wonder, Tenpecent conceived an incredible plot to have the magic robot steal masterpieces of art from the Museum-right under the noses of the police! Somehow, KADABRA could be in the museum while he was still on stage in the theatre: the best alibi in the world! Clearly this was a case for the greatest robot of them all, Astro Boy. Astro Boy was able to solve the case, all right, but only with inadvertent help form ABRA KADABRA himself!
