M-G-M's Lassie #29

In "The Sea Devil," Rocky and Gerry team up with Lassie and their old friend Buff Saunders on a tropical quest in Colombia to locate a long-lost Spanish treasure ship. When a sudden attack by a manta ray threatens their underwater search, Lassie’s quick instincts and courage come to the rescue—leading them to the hidden chest beneath the waves.

In "The Green Flame," Rocky and Gerry, accompanied by Lassie, journey to a supposedly abandoned Colombian emerald mine, where superstition runs deep. When the fearful miners prepare to burn rare plants in a desperate ritual, Lassie uncovers the truth behind the mine’s hidden riches—and the betrayal of its foreman, Valdo—leading to a quiet moment of gratitude and revelation.

In a quiet moment of moral reckoning, a hunter and his son Mateo face a wild bear named Reina—once a target, now a guardian whose memory holds a quiet power. When fate brings them together again months later, the past resurfaces in unexpected ways, testing what it means to see beyond fear.

In "The Race For Life," Lassie joins Rocky and Gerry on a trip to Quito, Ecuador, for the grand opening of a new railroad line—only to find tension brewing between chief engineer Vernal and worker Arbolon. When Arbolon’s gang sabotages a critical bridge during the trial run, trapping Rocky and Gerry, Lassie must use her sharp instincts to warn the approaching train, setting off a race against time.
