In the midst of this growing threat to the world's safety, a mysterious "Mr. Smith" (Martin Benson) arrives in the village. He is well-spoken, with little knowledge of ordinary life, but a great deal of knowledge about magnetic fields, while offering strong opinions about the dangerous experiments that Dr. Laird is conducting. Murray is positive that he is a spy, but Graham and Dupont decide that there is less threat from him than from the obstinate Dr. Laird, who plans on continuing his risky work. Even with "Mr. Smith"s dire warnings, the forest adjacent to the village is soon swarming with gigantic insects and other mutated monsters. Graham's and Dupont's best efforts fail to stop Dr. Laird, and so they alert the authorities to investigate and send in the military. Later, when leaving the laboratory, Dupont is threatened by the encroaching monsters and becomes trapped in the web of a giant spider. The army arrives in time and is able to destroy all the mutations, saving her life.
