Eccentric Professor Gibbs, brilliant but impractical, invents an invisibility machine and advertises for a guinea pig. What he gets is Kitty Carroll, an attractive, adventurous model, who thinks being invisible would help her settle a few scores. Complications arise when three comic gangsters steal the machine to use on their boss. But they fail to reckon with the Revenge of the Invisible Woman!

1963 film by Stanley Kramer
