Jon Hall returns, though not as Invisible Agent Frank Raymond, instead as escaped criminal Richard Griffin(no relation to the previous Griffins apparently) who finds refuge in the home of Dr. Drury(played by John Carradine) a kindly inventor who also has developed an invisibility serum, which he tests on Griffin, who then uses it to avenge himself on the treacherous couple(played by Lester Mathews and Gale Sondergaard) whom he blames for cheating him and leaving for dead. Griffin is already crazy, so the serum isn't to blame this time...Evelyn Ankers has a small role as a potential love interest. Poor entry was also the last, and it's easy to see why: below average F/X(visible wires in lifting scenes!) uninteresting and tired story, and a waste of good actors. No point to this one at all, and is best forgotten.
