Vet Dr. Philip Hansen diagnoses blind Hanne Seidel's guide dog Lupo incurable due to age. His assistant Bertie Heckenbichler has an instant crush on Hanne, who can't appreciate his looks, but his sweet nature and humor all the more. While Philip spends his day off helping the Kulka family manning the harvester, Pawel and the girls test possible canine successor candidates, to no avail, while regretting a pony was bought by a rich couple who don't even intend it to be ridden. Then it dawns both problems may solve each-other, so Bertie helps them raise cash to invent the guide equine.
