M-G-M's Lassie #24

In "The Warrior," Lassie and her friends accompany Senhor Rohas to Rio as his prized stallion, Warrior, prepares for the national cup race. When the hired jockey, Pedro Volta, is dismissed for cruelty, his resentment sets the stage for trouble—though Lassie remains determined to help Warrior succeed.

In "Jungle Rivals," Lassie and Timbu encounter the Juru tribe during a tense encounter with Dino, the chief’s son, who tests Timbu’s courage with a challenge. When Dino declares Lassie his rival’s good luck charm, the clever dog’s presence leads to an unexpected twist—only for Dino to fall victim to one of his own traps.
