The Son of Tarzan

Alexis Paulvitch, a henchman of Tarzan's now-deceased enemy, Nikolas Rokoff, survived his encounter with the ape-man in The Beasts of Tarzan and wants to even the score. He lures Jack, Tarzan's son, away from London and into his clutches, but the youngster escapes with the help of the ape named Akut.
