Several years have passed since Sawyer Nelson (Nathan Gamble) and the team at Clearwater Marine Hospital gave Winter the dolphin a prosthetic tail, thereby saving her life. Now however, a new crisis has arisen. Winter’s elderly surrogate mother, Panama, has died, which leaves Winter without a pool mate. According to USDA regulations, dolphins cannot be housed alone; unless a new companion can be found quickly, Clearwater will lose Winter to another aquarium.
