Episode Overview

A massive plant breaks free from confinement in the home of the missing scientist, Prof. Smithers. To combat this threat, Spidey steps through a portal in Smithers' house that transports him to prehistoric times. There, he encounters Smithers, who informs him that two radium gems embedded in an idol in a nearby city can destroy the plant if they are consumed by it back in New York.
