[2] Produced by Billi Productions, the film stars the voices of Sean Connery, Alan Cumming, Patrick Doyle and Kieron Elliott.

Set in the Scottish Highlands, the film follows Sir Billi, an elderly veterinarian who, with the help from his friend Gordon the Goat and the townspeople of Catterness, embarks on an adventure to rescue a beaver named Bessie Boo, while also helping her escape from a corrupt police officer.

[5] Sir William "Billi" Sedgewick works as a veterinarian and resides with Gordon, a goat who behaves like a dog, outside the small town of Catterness, located within the Scottish Highlands.

Billi organises a deputation in the town square before noticing McKenzie acting strangely and questioning his identity.

Victoria, a pilot duck assisting with the group's rescue, throws Billi a bottle of water, which he uses to revive Gordon.

[8] Peter Debruge of Variety called it "woefully anaemic", criticising its "simplistic story and non-sequitur style".

[14] Tracy Moore of Common Sense Media gave the film a 2 out of 4 star rating, writing: "GUARDIAN OF THE HIGHLANDS has a bit of an identity crisis: It's an animated children's movie about saving an endangered beaver but with the winking sultriness at times of a grown-up action movie.

It borrows heavily from James Bond in the introduction, action, and treatment of female characters, who are often shown with heaving, exaggerated cleavage.

There are some nice ideas about preserving wildlife and endangered species, and the community must work together to save the day against the evil corporation and corrupt officers.

But there's a bit of a mishmash of action and jokes here without a lot of meaningful plot development and some iffy portrayals that muddle the positive messages".
