Ranger Bob und sein Kollege Al reiten, in Begleitung von Lassie, am Strand entlang. Sie treffen auf eine alte Dame, die verzweifelt ihr Kätzchen sucht.
Lassie twice comes to the rescue of a stray kitten that is first attacked by an angry hawk, then trapped in a cave by rising tides. The collie also finds time to retrieve a forest ranger's horse that has broken loose from his tether.
