M-G-M's Lassie #22

When a playful encounter with a troop of howler monkeys takes a sudden turn, Lassie must track down the stolen camera—and then leap into action when a harpy eagle snatches one of the little monkeys. With quick thinking and her usual courage, she’s determined to bring them both back safe.

Dr. Blithley, a botanist from the National Botanical Institute, arrives at the homestead seeking rare jungle specimens—only to be convinced to take Timbu and Lassie along on his day-long expedition into the wild. As the trio ventures deeper into the untamed green, the true spirit of the jungle begins to reveal itself in ways neither human nor dog could have expected.
