Breath-taking encounters with enormous manta rays and ground-breaking research are showcased.
"Giants of San Benedicto" features Dr. Robert Rubin and his ground-breaking research on giant mantas. The remote Socorro Islands off Mexico's Pacific coast are the scene of breath-taking encounters with enormous manta rays. These majestic giants actually invite human contact, and encourage certain divers to ride them. The film crew also travels to the Bahamas to visit 'Bubbles', a 15-foot manta in the world's largest aquarium, and witness her release back into the ocean.
