The New Adventures of Lassie

It’s "Adopt-a-Puppy" day and Zoe and Harvey host Olive and her father who have come in search of a new family friend. But the puppy Olive falls for does not turn out to be as courageous and Lassie-like as her father would have liked. Zoe relives the first time she met her beloved dog, at the same time as her best friend Harvey, who had just arrived in the valley!

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.

It's Harvey's birthday and his mother offers him his maiden flight in a hot-air balloon. Of course, Harvey instantly thinks to invite Zoe along to share his dream-come-true! While Harvey is over the moon, Zoe is afraid and she shares her fear of flying with Lassie. She cannot however bring herself to confess her fear to Harvey and runs away just before take-off.

After Lassie helps a young horse-rider to control her unruly mustang, Zoe and Sarah take her in as the horse rests. But when two brothers turn up in the valley in search of their stolen mustang ,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.

Today is Halloween! Zoe seizes on the opportunity to prove to her mother how grown-up and responsible she is by chaperoning Mrs. Lee's niece on her trick-or-treat trip to the neighboring town alongside Harvey and Lassie. Zoe and Harvey are soon overwhelmed by the little girl's unpredictable behavior and soon lose track of her! Fortunately, Lassie is on hand to save the day.

While Harvey is on vacation in the Caribbean for the winter, Zoe has to help her father to secure the park before the arrival of a blizzard. When Zoe leaves the rangers' station to save a wolf-cub, she becomes trapped in the snow storm. Fortunately, Harvey is never far away and Lassie, as ever, is there to help.

Zoe and Harvey set out to investigate theft from the park archaeological site. The pair soon finds themselves in big danger and Lassie is faced with a huge dilemma when she finds she cannot save both of them. Lassie has to use great cunning and aplomb to save the kids from their predicament while also putting a stop to the thefts.

Zoe decides to pursue the family tradition by winning the Park's legendary blueberry pie competition. To achieve this she has to bring a special personal touch to the family's award-winning recipe. But when Samantha arrives with the recipe by a top-chef in hand, Zoe begins to doubt she has the ability to find her own special twist to make her pie the best.

While helping establish a new nature preserve on the edge of the Park, Zoe, Harvey and Lassie meet the scientist, Doctor Dudley, an eccentric recluse who has recently moved to the valley. Convinced the whole scheme is a fraud, the doctor is reticent about the project and refuses to sell his land to the environmental organization behind the nature preserve.

When Zoe and Harvey visit the new dam at the edge of the park, the noises emanating from the construction upset Lassie who refuses to go any closer. When she understands the valley can be flooded due to Nick's error, Lassie has to draw on her inner strength to overcome the stress the sounds of the dam are causing her and save the kids trapped inside the dam.

Zoe, Harvey, Graham, Beth and Lassie are forced to interrupt their hike on the valley glacier when they notice that its peak is in danger of collapsing. Beth seems hugely upset at the idea. Later, when Lassie notices Beth's car parked at the foot of the glacier, Harvey realizes that his mother has been hiding something from him. Despite the danger, he sets out to look for her with Zoe and Lassie.

To perpetuate his father's own passion, Harvey decides to enter the photo competition for the Park's Visitor's Guide. When he finds out about his rival - Samantha's- high-tech equipment, Harvey asks Doctor Dudley to tweak his camera to be able to take spectacular photos, even if it means putting himself in danger.
