Dr. David Nathanson, an American paediatrician, firmly believes in the therapeutic qualities of the gentlest of animals, the dolphin. His idea was to bring physically and mentally handicapped children in contact with the dolphin to help them improve their mobility as well as their mental faculties. It all started 20 years ago and the results proved him right: the children made considerable progress through the playful contact with the animal and even draw comfort from its gentle behaviour. Patients from all over the world come to him, accompanied often by their parents. The film observes not only the interplay between child and animal, but also the dedication and patience of Dr. Nathanson’s staff. The waiting list is long, up to seven years! Therefore, a second therapy centre has just been opened in Florida.
