Land of the Giants

On Barry's birthday he is stricken with a case of appendicitis. None of the Earthlings have medical training, so Steve will have to operate unskilled. They need ether, so they go to a nearby hospital only to be seen by a giant doctor, Brulle. He insists on helping, in return for the Earthlings translating a medical book found from a previous crash.

The hospital janitor spots them, but the little people drive him off with ether, so that they and the doctor can escape and rendezvous somewhere in the woods away from the campsite. While the police close in, Steve operates on Barry under the doctor's guidance. The operation is a success and the doctor runs off to draw off the police since Barry can't be moved.

Brulle is shot and captured, and gives the police misleading directions to the Earthlings. Left behind in handcuffs, the little people thank the doctor as he relates his world's version of the Hippocratic Oath as his reason for helping them.
