A botanist breeding a monstrous carnivorous plant spars with his assistant, in the isolation and oppressive heat of their research compound in a remote sector of the Amazon. Dr. Alden's gleeful obsession with his hybrid plant buoys him along, until his aide Merriman's boredom inspires a means to play on the older man's weak heart and narrow mind. 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.
