A family of St. Bernard dogs lives high in the Alps; all have saved many lives, except for the diminutive and not to bright Little Cesario. We see the dogs set out to work; the hapless Cesario keeps getting in the way of the top dog, Big Alexander. A blizzard hits, and Cesario runs back to the monastery as Big Alexander trudges on. From the monastery, he can see Big Alexander trapped on a ledge. He rushes to the rescue, turning into a giant snowball that knocks Big Alexander from his perch just as a landslide crushes the location. Little Cesario finally has a saved life to his credit.
