A man is sentenced to prison for a murder he did not commit. Thanks to a serum invented by his brother, he manages to become invisible and escape from prison in order to prove his innocence, while his brother works feverishly to find an antidote. Theatrically released in USA in Spanish language only; later English-dubbed version syndicated directly to television.
