One of the best action pictures, with Rin-Tin-Tin as the star, that have been turned out in this series.
It’s a story of Kentucky, as the title indicates [adapted from the story The Untamed Heart by Dorothy Yost]. A little puppy is turned loose by a little boy because his father commands it. When the story itself starts this pup has grown to be the leader of the pack and is known as the Grey Ghost.
In a part of the hills are two Harley brothers, one inclined to be a bully and other a rather diffident youngster. There comes into the picture at this time a young school teacher with her crippled child brother. Both of the Harley men fall in love with her.
There is a moment when there are three suspense sequences being carried on at once: the two brothers fighting over the girl in the woods, the dog swimming down the stream toward the falls for the youngster’s crutch and the little fellow himself trying to fight off the dog pack. This carries a wallop.
