Nancy has her own medical laboratory for experiments in the Artic. She also has the invaluable help of her St. Bernard, Berni. Berni is a very intelligent dog and thanks to his hearing acuity is, he’s able to hear the cries of the poor wolf cub, Lobi, who is stuck on a rock.

Berni comes out quickly to help Lobi with the rescue sled. Berni can get Lobi rid of the trap and take it to the Nancy’s camp.

There, Nancy finally heals Lobi. Nancy washes Lobi, checks the temperature, provides oxygen, takes the radiography and places a cast on Lobi’s paw.
