Rockland Stone, also known as Machine, has devised a particularly cruel scheme this time: he uses sonar to disorient the whales. The crew from Misty Island attempts to assist a stranded whale, but their efforts quickly become nearly impossible. Suddenly, Rockland Stone arrives and offers his help with the rescue operation. Everyone is excited about his offer—except for Willy, who suspects the true intentions behind Stone's facade as an environmentalist.
