Tarzan and the Slave Girl

The Lionians are kidnapping women because a deadly disease has decimated their female population. Their chief Abducts Jane and Lola, along with other women from nearby tribes, to repopulate the tribe. The disease kills within hours and has already wiped out many Lionian women, leaving the men desperate to preserve their people.

The film opens with a local tribal girl vanishing, establishing the kidnappings as the central threat.

The Lionians are struck by a deadly disease that can kill within hours. It has already claimed the life of the Lionian king and many women in the tribe. Dr. Campbell possesses a serum capable of both curing the disease and vaccinating against it, which becomes crucial to resolving the film's crisis.

The mysterious illness is introduced early as the reason behind the kidnappings.

After the Lionian king dies from the disease, the Prince takes control. The ruthless counselor Sengo manipulates the grieving Prince by encouraging his desires for food, drink, and women. When the High Priest challenges Sengo's schemes, Sengo convinces the Prince the priest is a rebel and has him fed to the lions, then assumes the High Priest role himself.

Sengo is present as a counselor from the start, subtly influencing the Prince.

During a chase through Lionia, Tarzan hides inside the dead king's sarcophagus but gets entombed when the Lionians seal it. He later discovers Jane and Lola have also been sealed in the same mausoleum after fleeing Sengo. Tarzan frees them, and they summon help by calling out. An elephant is brought in and tears open the tomb door, freeing all three.

The tomb sequence is set up when Jane and Lola hide in the Queen's mausoleum to escape Sengo.

Dr. Campbell accidentally drops the serum bottle during the jungle pursuit. Neil, who was left behind due to a leg injury, discovers the missing bottle while trailing the group. Cheetah, Tarzan's animal companion, then finds the serum along the way, allowing Neil to deliver it to the Prince's son in time for treatment.

Campbell drops the serum bottle during the difficult jungle march, creating an early complication.

The Prince frees Tarzan, his friends, and all the captive women because the serum successfully cures his son from the deadly disease. Recognizing that Sengo manipulated him and caused the crisis, the Prince orders the High Priest (Sengo) killed and justice restored. The Prince's son being saved changes his perspective entirely.

The Prince's love for his sick son is established early, making his recovery the turning point.

After Lola taunts Sengo and is whipped, Jane fights back by stabbing Sengo with his own knife. The two women flee into the dead Queen's tomb to hide. Sengo discovers them and seals them inside the mausoleum, entombing them alive. They are later found by Tarzan, who breaks them out.

The catfight between Jane and Lola during their capture sets up their rivalry.

Neil suffers a painful leg injury during the trek through the jungle and the repeated ambushes by rival tribes and Lionian forces. He is left behind for a time to recover, but he continues following the group and later plays a crucial role by recovering the serum and delivering it to save the Prince's son.

Neil's rough-edged nature and drinking habit are established early, but his loyalty proves valuable.

Lola is Dr. Campbell's native assistant, a half-breed nurse who accompanies the rescue party. She has romantic feelings for Tarzan, creating tension with Jane. During the raid, both Jane and Lola are captured after a catfight. In Lionia, her defiance of Sengo leads to her being whipped, but she remains courageous throughout.

Lola's romantic interest in Tarzan is introduced early, creating jealousy with Jane.

In the final confrontation, Tarzan holds off the Lionians and defeats Sengo by throwing him into the lions' pit. This acts as poetic justice for the villain who had the High Priest fed to lions and orchestrated much of the film's conflict. Sengo's death marks the decisive end of the villain's threat.

Sengo's rise to power involved having enemies fed to lions, setting up his own fate.
