Rugged, unique, unconquerable. Baja California the only North American land that turned back the Spanish Conquistadors. This desert peninsula has repelled waves of humankind, leaving its marine ecosystems intact and filled with life. From manta rays to dolphins, Baja is sanctum to some of the most spectacular marine life on earth. Here swim sperm whales and pilot whales, along with the most colossal animals living on earth, the elusive blue whale. But it is the gray whales which breed only at Baja who are the stars of the film as they deliberately approach whale watching boats, allowing occupants to touch them.
