 The weather forces a mail plane to turn back. It drops the mail at Outpost #5, staffed by Pluto, who is to carry it to the next airport. His mission is briefly thwarted by a totem pole (hence, this is probably Alaska), but his real enemy is a rabbit who covets the blanket on Pluto s sled. They chase each other down some treacherous winding slopes before they end up at the landing strip, where the two of them crash into a snow bank and send the mail pouch right into the pilot s hand.
