Sweater

It is August and everyone is taking off for the summer holidays. As his owner drives through Paris with the windows down, Sweater lets his tongue hang loose and takes in the sweet smells of summer.

But when the two are separated at the train station, Sweater sets off to find him, following his nose. By evening, far, far away at a station in the outskirts of town, Sweater must accept a painful truth: he has lost his owner. There he meets a chihuahua named Groucho, who invites him back to an abandoned train car hidden in the woods, a makeshift home for wayward dogs.

Sweater continues to search for his owner. But if this coterie of lost canines isn't the family he'd imagined, it may be just the family he needs.
