Faced with performing a very difficult brain operation on an important scientist, a neurosurgeon is given a pair of glasses with special powers. A crystal egg reveals live tableaux of the planet Mars. A 19th Century scientist is obsessed with investigating the crystal, but the antique shop owner who came across the seemingly worthless glass hopes to sell it ASAP to a tall, insistent stranger, for whom no price is too dear. The delay while the scientist experiments on the egg makes the buyer even more desperate.
