Jock , the border collie, tends sheep as he has been trained to do by Old Tom. One day he returns from rounding up strays to find the humans gone, all other dogs dead, and where the mud-hole had been, the nose of a volcano pouring hot lava into the sea. His faithful devotion to the sheep in danger and desolation, and its reward in friendship and hope at last, make a story to be long remembered.
