In Alberta, Canada’s Jasper National Park, Kate begins Alpha school with her father (Winston) and grows up as a fully trained Alpha. On her first hunt, she crosses paths with two wolves from the Eastern pack who are lacking food in their own territory and nearly start a war, but the fight is broken up by Kate’s childhood friend, Omega wolf Humphrey, who has feelings for her, but can’t pursue a relationship with her because it’s forbidden for an Alpha and Omega to be together. The two packs have had a bitter rivalry ever since Tony commanded the Eastern wolves to cross over into Western territory (against pack law) to get sufficient food. Winston and Tony meet up one night and arrange for Kate to marry Garth (Chris Carmack), Tony’s son. Kate, having a sense of responsibility and duty, agrees for the good of the pack and meets Garth at the Moonlight Howl.
Garth seems perfect, except that he has a terrible howl and is not very bright. Kate, taken aback, leaves and has a talk with Humphrey about Garth, when suddenly they are tranquilized by some park rangers and taken away to Sawtooth National Recreation Area in Idaho, where they meet goose golfer Marcel and his duck caddy Paddy. Humphrey and Kate learn that they were relocated to repopulate the species. This horrifies Kate, but intrigues Humphrey so that he can be with Kate, but after coming to an agreement, Marcel and Paddy help the wolves return home to Jasper Park.
The two packs discover that Kate has gone missing. Tony warns Winston that on the next full moon if Kate doesn’t return to marry Garth, war will be declared for their territory. Kate’s sister Lilly however has developed a crush on Garth and suggests that she show him around until Kate gets back.
