In northern Quebec, the female caribou of the Leaf River herd are on epic 600-kilometre migration to reach their calving grounds. They are racing against the clock to complete their journey before the spring melt begins. Along the way, they must face off against an ancient adversary that hounds them their entire lives – wolves.
In northern Quebec, the female caribou of the Leaf River herd are on epic 600-kilometre migration to reach their calving grounds. They are racing against the clock to complete their journey before the spring melt begins. Along the way, they must face off against an ancient adversary that hounds them their entire lives – wolves.
The journey begins in the offshore waters off the Pacific Coast of Canada, where four thousand Steller sea lion pups have just been born on a remote island. The boisterous sea lion pups are facing the danger of swimming in rough seas – but an even greater threat is lurking in the water — killer whales. An incredible hunt unfolds when a family of killer whales launches a stealth attack on the sea lions.
