Pettson and Findus are fishing down by the lake when suddenly a snowstorm rises and it starts to get dark. Lost in the bad weather they are forced to seek shelter in an igloo they build out of blocks of frozen fishes. Inside they tell stories from the past year to keep their spirits up.

Eccentric old farmer Pettersson and his cat, Findus, have hilarious adventures camping in the woods while waiting for a letter from the king.
