Birdman and the Monster of the Mountains.When a village in Tibet is regularly terrorized by a monster, Birdman and his friends Birdboy and Avenger follow the giant tracks and encounter him. As Birdman fights the monster, Birdboy is taken captive by the real villain, an exploiter who has created this mechanical giant to frighten the villagers away from town and the uranium deposits nearby. Smashing the monster, Birdman is cornered by the villain and his uranium ray, but Avenger saves the day by surprising the aggressor, who is downed by his own ray. The grateful villagers thank the heroes for removing the threat over them.
