In the 'Return Of Rin Tin Tin', we meet Paul, a young war orphan recently given over to the care of kindly Father Matthew. Unable to deal with all that has happened to him in his short life, Paul retreats from the world until meeting Rin Tin Tin, who immediately befriends him and pulls him out of his shell. Trouble appears in the form of Rin Tin Tin's original owner who wants to take him away. Heartbreak and a climatic final showdown add up to a feel-good ending that will endure long after the credits roll.
