After her grandfather's death, twenty-year-old Alma decides to return to her childhood home - a small island in the heart of the magnificent Canadian forest. While there, she rescues two helpless cubs: a wolf and a lion. They form an unbreakable bond, but their world soon comes crashing down when a forest ranger discovers the animals and takes them away. The two cub brothers now have to embark on a perilous journey across Canada to reunite with each other, as well as with Alma.
Nakon djedove smrti, dvadesetogodišnja Alma odlučuje da se vrati u svoj dom iz djetinjstva - malo ostrvo u srcu veličanstvene kanadske šume. Dok je tamo, ona spašava dva bespomoćna mladunca: vuka i lava. Oni stvaraju neraskidivu vezu, ali njihov svijet se ubrzo ruši kada čuvar šume otkriva životinje i odvodi ih. Dvojica braće mladunaca sada moraju da krenu na opasno putovanje po Kanadi kako bi se ponovo spojili jedni s drugim, ali i sa Almom.
