James Moskito and other brave volunteer divers work to free a drowning humpback whale entangled in crab nets and a 3000lbs anchor near the Farallon Islands, off the coast of San Francisco, California. Facing a massive, frightened animal, shark infested water, and freezing temperatures, the team of heroes work for 5 hours to free the animal. Upon the final cut, the whale returns over and over again to gently nudge each diver.
