Release Message:  After inadvertently unleashing a giant plant on the city from a seed, Peter Parker (Paul Soles) travels back in time to 3,000,000 BC in order to find the missing scientist.

Description:  After inadvertently unleashing a giant plant on the city from a seed he found in the house of a missing scientist, Peter Parker travels back in time to 3,000,000 BC in order to find the professor himself. Spotting a great stone city in the distance, Peter quickly doffs his school clothes to reveal the costume of Spider-Man and, after a battle with an amphibious monster, is captured by a tribe of primitive blue giants. Taken prisoner to the city, Spidey discovers that the professor has become the benevolent ruler of giants and asks for help. The scientist reveals he destroyed the plans with radium. He explains that the only way to stop the menace is to steal radium gems from the temple of an evil society of intelligent plant monsters, which were mutated by its radiation and captured the city from its original inhabitants. Spider-Man is knocked out by the plants and put in an arena with 'Goliath', a giant caterpillar-like monster, for the amusement of the Master Vine. After a brief battle, Spider-Man webs up the beast, defeats the plant soldiers and takes the radium gems, which are the eyes of a huge statue. The plant civilization, dependent on the radiation for survival, withers away. Having returned the prehistoric city to its rightful owners, Spider-Man returns to the present and feeds the radium gems to the giant rampaging beast. Unable to absorb so much energy at once, it too withers away, saving the city once again. (time portal to ice age)
