In his laboratory, the Professor Deemer leads secret experiences. He tests on all sort of animals a product that increases their growth in an incredible manner. There, it is possible to find rats, Guinea pigs and a tarantula of a gigantic size. But animals are not the only to have tested the product. Paul Lund, the assistant of Deemer rises suddenly, the deformed face and attempt to kill the Professor. In the struggle, the assistant will find death and the giant tarantula will escape Deemer's laboratory. This one will choose not to warn the Sheriff so as not to compromise his experiences.

But the Doctor Matt Hastings does not believe to Deemer's diagnosis concerning Jacobs's death. A crushing acromegalia never happens, it is a rare sickness that transforms a person very slowly. Hastings meets Stephanie Clayton, a student who realizes a thesis in biology and who has been engaged for the summer by Jacobs to work with him. While accompanying her to Deemer's laboratory, Matt Hastings announces her the death of her employer.

In Deemer's laboratory, Stephanie begins to work. She quickly notices what type of experience Professor Deemer is realizing. But the former has the face that changes more and more, such as if it was deforming.

By his side, the Doctor Matt Hastings inquires with the Sheriff on strange phenomenons. The cattle of a farmer have been devouring, and only bone stays. An other farmer and the two passengers of an accidented vehicle have equally been devoured by an unknown sort of animal. What is breathtaking, it is that we find identically around victims a product that is some kind of insect venom, what confirms the Arizona Institute of Agriculture to be tarantula venom.

DoctorSF's Words

In this movie, it is nice to see the figuration of the uncredited Clint Eastwood, the Jet Squadron Leader who bombs the tarantula, at his beginnings for cinema.
