During a terrible storm some mares were killed by a falling tree. Murgatroyd, the terrified foal of one of them, escaped into the bush. His sire had been a Sydney Cup winner and the station manager was sorry to lose him. A year later Murgatroyd is identified by a stock man and the manager sends out three parties to try to capture him. They all fail and the manager asks a shooter to kill the horse because the horse had taken some of the station horses. The shooter fells the horse carefully so as not to cause it permanent damage and trains him with the view to racing him.
