George has always wanted a dog, so when he picks up small Renni, the runt of a litter of German Shepherd puppies, he immediately falls in love.

As Renni grows, George begins to teach him, and soon Renni is able to do remarkable things. When a trainer suggests Renni become a rescue dog, George knows it's a perfect fit for his pet. Soon Renni is able to find anyone in any situation.

Then the war that has been looming finally begins, and Renni and George enlist. They are able to help many soldiers during training camp--but when they are tested in the actual battlefield, can the two friends hold their ground? Or are they unprepared for the trials ahead?
