The leopard men attack the treehouse and, rather than retrieving Tarzan (as the gang expects), make off with Jane, and gas the others. Once conscious, Tarzan, Tantor, Terk and the Professor set off for Opar to rescue her, only to find Queen La, staffless and at the mercy of a leopard, begging for help. Despite the Professor's warning, Tarzan intervenes and forges a temporary alliance with La to free his wife from La's rebelling minions. However, he is unaware of the true intentions of La and the leopard men.
