The alpha female, heavily pregnant with cubs, is banished from the pack, and must journey through the frozen Alps in search of a new life.
She travels up to 40 miles a day, venturing into new countries and battling severe weather conditions and other predators to stay alive.
Partway through her journey, she gives birth to six cubs, who she must feed and protect.
