Action packed serial with the usual cliff hangers and unlikely escapes. Tarzan (Frank Merrill) faces the menace of the Arab army of Queen La of Opar (Lillian Worth). Jane (Natalie Kingston) is kidnapped and Tarzan suffers an amnesia in the usual movie way, a blow to the head!
After several chapters as a rather vague simpleton Tarzan is finally back, cured of his amnesia also in the usual movie way (another blow to the head natch). Can Tarzan rescue Jane, resist Queen La and get his hand on the wealth of Opar?
The first sound Tarzan in a way, not a full talkie rather a transitional silent film with added sound effects including Tarzan's yells! Merrill brings some impressive physicality to the role though not much in the way of acting. However for the role he is perfect.
