Explorers near the North Pole make a startling discovery: a perfectly preserved prehistoric dinosaur-like animal, frozen in ice. This invaluable discovery is brought to Metropolis, where the experts at the city's museum can study it more closely. Lois Lane, a reporter with a nose for news, is of course on the scene. Although she's all business, the engineer to whom she is speaking gets distracted by her shapely gams as she climbs the stairs in front of him. Not noticing what he is doing, he sets his oil can down precariously on a ledge; it gets knocked off into the engine which controls the museum's freezing unit and knocks the unit out altogether. The engineers work to restore power quickly, before the temperature rises and the ice surrounding the monster melts -- but to no avail. Freed from centuries in his frozen prison, the giant goes on a rampage throughout Metropolis. Fortunately, Superman is quickly on the scene, and although he gets sidetracked rescuing Lois -- who is determined to be in on the action so that she gets the best story -- he eventually defeats the reptile and all turns out well.
