Panama Menace is the reissue title of PRC's South of Panama. Secret agent Roger Pryor is dispatched below the border to protect an important scientific formula. Believe it or don't, this mixture has the ability to render things invisible. Enemy agents, Lionel Royce and Lucien Prival want to get their mitts on this vital secret. Femme fatale Virginia Vale spends most of her time cowering the corner, allowing two-fisted Pryor to make the world safe for democracy. Watch for Beaver Cleaver's future dad Hugh Beaumont in a minor role.
