A man rides a horse as his dog runs alongside. He stops, dismounts, walks with his dog and perches on a rock, looking down at 200 wild horses grazing in a canyon. Men are then shown riding horses. One cracks a whip in the air. They are rounding up the wild horses into a corral. This is done in cuts with different shots of the cowboys and horses in action. Two cream-colored horses manage to break away. A cowboy goes after them, trying to find them. When twilight turns to dark, he gives up the search. The mother and daughter take a ride to the local mailbox with the baby kangaroo, in his sack, between them in the front seat. Mom says to put him outside in the open bed of the truck so he'll get used to the elements, otherwise he won't be able to survive winter in the bush when they eventually release him. The girl does so, hanging the sack on a truck bed post and the kangaroo swings happily, back and forth. The next scene includes shots of horses running through the snow, searching for shrubs, finding some and eating what they can and then, a little horse lying down in the snow, supposedly dying from hunger and cold. (The narrator tells us the following: The horses are desperate to survive the winter. The head stallion, who serves as the leader of the herd, must decide whether to stay put and starve, or look elsewhere for food, putting them closer to man, who will try to capture them, or to go into the territory of other horses who will fight them to protect their scarce shrubs. The leader takes them to other horses' territory. The two head stallions "fight" for dominance. This scene is shot in cuts, showing the horses rearing and "nipping" at each other. The herd can graze safely for shrubs after the first stallion wins and the other backs away. The girl holds the kangaroo in her lap, petting it, as her mother tells her she must release him soon. Cowboys are attempting to break one of the wild horses they captured. This was done in cuts. The lead cowboy's horse bucks, throwing him. He becomes enraged and whips the horse with a rope. (The whipping looks fake to me.) Afterwards, the little girl, who was there to watch at the invitation of the cowboy, tells her mother she thinks the way they break the horses is mean and cruel. The mother says that it's just the way it's done. The girl insists that it's still cruel. Two years later, the head cowboy keeps chasing the son of the lead horse who escaped in the beginning. He is now fully grown and beautiful. One scene shows the cowboy and his horse jumping into a stream giving chase to the young stallion, as a flock of birds fly overhead. The young stallion's father, who is the original lead horse, must defend his position against a challenger. They rear at each other, nipping at each other's necks. The leader becomes weak and tired and falls down. He lays down and after hours, finally dies. The young stallion, whom the people call the "Cream" and "The Silver Brumby", watches and sees his father die. He starts building his own herd of mares and fillies by marauding other stallion's herds. This is not depicted, but told in narration. Cowboys walk horses around inside a corral at an auction. A nice cowboy buys a beautiful cream filly and breaks her gently out in the wilds with his dog and his own horse nearby. The cream stallion is out there watching her from a distance. As the man and his dog are sleeping in the doorway of the front porch of his cabin, while the moon is full, the stallion is right out there pawing and calling to the filly. He jumps the fence into her corral then jumps out. The man wakes up just in time to see his filly jump over the fence. He tries to run after her, but she follows the stallion into the hills to join his herd. Back to the kangaroo hanging in the sack, attached to the mother's bedroom door knob. It's winter again. The stallion keeps his herd moving through the snow in search of better pastures. The cream mare isn't used to winter in the wilds. Mom and daughter walk in the wilds with the young kangaroo. They release him from the bag. He goes over to a larger kangaroo standing nearby. The cream mare returns to her original master's ranch when she becomes pregnant. The stallion is very upset but she needs the comfort from the elements that the cowboy can provide. He helps the mare give birth to a golden filly. The stallion comes back near the barn checking on his mare and their off-spring. The cowboy mounts his ride and, accompanied by his dog, takes off in pursuit of the stallion. Actually, the stallion is purposefully leading the man on a long chase which continues for hours. A rain storm begins as the sun goes down. The stallion disappears from the man in an extremely remote section of the high country. The dog continues running with the cowboys and his horse, but they are lost. The horse comes back to the corral where his mare and daughter are. Lightning strikes the corral, knocking down the fence. The mare and filly escape with the stallion. The man leaves the valley until next spring. Another stallion tries to steal the silver stallion's mares while he is gone, but he returns and chases the interloper away. There is a shot of the horses running across a stream and rearing at each other as the two stallions fight for supremacy. They do not fight to the death, but the silver stallion beats the other horse, the same one who had killed his father in the previous fight. This scene was shot in cuts. With the arrival of spring, the man and his dog return to the valley, accompanied by the best tracker and rider in the high country. He intends to re-claim his mare and filly, but more importantly, he wants to capture the silver stallion. The mother and daughter pray that the silver stallion is both smart and brave enough to outwit the men. In the final scene, the two men go out on horseback, with the dog, looking for the stallion. They spot him, chase him, lose him and start tracking him again. The stallion sees them, but they don't see him. The see him again and pursue him. The man cracks his whip in the air as they run. The stallion stays about 50 feet ahead all the way. He approaches the edge of a cliff and, to the astonishment of the pursuers, he keeps running and jumps off, never to be seen again. This scene was shot in cuts. The horse is seen from behind, going over the edge of the cliff. It is not apparent how far the horse jumped or where he landed, as this was not shown. It is possible, from the way it appears, that the horse jumped only a few feet and landed without danger or injury. This is, however, unconfirmed. The rider tells the mother the stallion was a ghost of the horse who jumped off the cliff rather than be captured. The mother and daughter cry on their front porch. Then, as they begin to hear the call of the silver stallion in the distance, they begin to smile. The legend of the silver stallion spreads throughout the region.
