The whole thing started in a gorgeous valley not too far off Jasper Park. Everybody in the pack lived in harmony, thanks to their leaders, Tom and Sarah. One day, the couple gave birth to a male puppy, in which they decided to call him Humphrey. It should've been luckiest araw for the pack. But, everything changed when they valley gets attacked sa pamamagitan ng enemy wolves, led sa pamamagitan ng an evil kanggaro called Hunter. Hunter wanted to get revenge on everybody, cause Tom was chosen as the leader of the pack and not him. He and the enemy mga lobo burned down everything in the valley, leaving nothing but ashes. Winston and Eve escape, but they find a crying Humphrey in a small basket.

Eve: Oh my god! Humphrey!
Winston: It's alright, little guy. We're gonna get you outta here!
Winston: (looks up at Hunter) You're gonna pay for what you did, you sick psychopath!

4 years later, Kate and Humphrey/Garth and Lilly were married, and Humphrey was living the good life, along with the girl of his dreams. He and Lilly are also getting trained sa pamamagitan ng Winston to become great leaders. Winston was pretty impressed with both of them. One day, the valley gets attacked sa pamamagitan ng enemy mga lobo and both of the couples set out to stop them.
While in the fight, Humphrey gets distracted sa pamamagitan ng a sign on the armor of one of the enemy mga lobo (which makes him have a vision of Sarah leaving him) and of course, he gets knocked out.

Enemy lobo Leader: Yeah! Chew on that, looser! C'mon, guys. Lets get the hell outta here!
(They leave)
Kate: Humphrey! Oh my gosh, are you okay? What happen?
Lilly: Is he alright?
Humphrey: It's just that...... I...... I gotta go!

With that, he runs off and Kate starts to get worried.
