Rex Steele: Nazi Smasher(2004)

Rex Steele: Nazi Smasher is an animated short that recreates the style of 1940s superhero serials. In Chapter 13, "The Bosom of Terror," Rex and his assistant Penny travel to South America to stop the villainous Eval Schnitzler and his henchwoman Greta Schultz from using a massive drill to breach an active volcano and unleash its magma. The drill lies hidden within a mountain temple adorned with strange statues of Indian women. When Rex and Penny crash-land in the jungle, Rex ventures into the temple to investigate while Penny works to repair their aircraft. The episode captures the campy action and cliffhanger thrills typical of mid-century adventure serials.
