Phillip Reed ("Osborne") is determined to charter a boat and return to a mysterious island he accidentally discovered during his wartime exploits. With the help of some cash from girlfriend "Carole" (Virginia Lane) off they set, and upon arrival we get a sort of "Lost World" (1925) derivative as the crew struggle to survive the beasties they discover and the avaricious antics of their dipso captain "Tarnowski" (Barton MacLane). The animation for the creatures they discover is adequate - rather static and one dimensional, and the dialogue and pacing of the 75 minutes or so make it quite a long watch. It's fun for about twenty minutes towards the end, but otherwise this is sadly just an unremarkable feature.
