Dr. Griffin, with no other motive than curiosity, undertakes research on the concept of invisibility. Having become invisible, he finds himself in an unfortunate combination of circumstances consisting of being suspected of murder and hunted down, forced to abandon the notebooks containing the notes of his experiences that would enable him to carry out the opposite process. His former classmate Dr. Kemp promises to find them, but in fact intends to use them himself in search of absolute power.
