Lassie

Olive and her father listen as Zoe relates how she and Lassie were trapped by a forest fire after Harvey had left them to seek help. While young Lassie demonstrated her extraordinary devotion to help the young Zoe from her predicament, our heroine once more demonstrates her mettle when Olive's puppy gets lost in the park and Zoe is called upon to find it.

Now that Zoe and Harvey are old enough to take part in the Grand Mountain treasure hunt to celebrate the founding of the park, they are determined to win the race with Lassie's help. While Zoe shows her headstrong nature by turning down her mother's help, doubt soon sets in when her big rival, Samantha, somehow manages to stay one step ahead of our heroes on each challenge.

After Lassie helps a young horse-rider to control her unruly mustang, Zoe and Sarah take her in as the horse rests up. But when two brothers turn up in the valley in search of their stolen mustang -presumed culprit: a young girl- Zoe realizes it's her new-found friend, who has now suddenly disappeared. Lassie encourages Zoe to listen to her heart and our heroic trio sets off in search of the girl.
