A man wrongfully convicted of murder take the invisibity potion to escape the electric chair and find the real killer before he gose mad. Whilst the plot is not the best, there are good invisibility effects which received an Oscar nomination. Vincent Price gives a good performance even though a lot of the time it is just his voice.
