Kate and Humphrey are eager to spend the upcoming winter with their three pups, Stinky, Claudette and Runt, as it will be the first that they’ve spent together as a family.
While out travelling with his siblings, Runt, the only Omega offspring of Kate and Humphrey, climbs a tree and spots 3 rogue wolves in the area. After 2 of the rogue wolves save Stinky and Claudette from a grizzly, Runt suddenly disappears. Stinky and Claudette then inform Kate and Humphrey, including their relatives as they were about to have a family dinner, about Runt’s disappearance. The family hurries to find Runt, and Kate sees that the rogue wolves have captured Runt and are heading to Banff National Park, home to the rogue wolf pack and south of Jasper. After being warned by Tony and Winston about how dangerous the rogues are, Kate and Humphrey still go on to find their lost pup, much to their disappointment. Meanwhile, at Banff, Runt is taken to the rogues’ leader, King. He is then made as a bait, as King expects the western pack to come for Runt. Princess, King’s daughter, is appointed to care for Runt and to keep the bait alive. As night falls, a storm approaches, prompting Kate and Humphrey to stop the search and wait for the storm to subside the next day. Meanwhile, at the den, Stinky and Claudette sneak out to help their parents search for Runt while everyone is asleep.
