Man from Atlantis S01E01 - Melt Down

Water levels are rising all over the Earth. Mr. Schubert offers to stop the disaster in exchange for Mark Harris, but it's the villain himself who is melting the world's ice caps with microwaves. Schubert agrees to stop the melt down if Mark will stay on of his own free will as a test subject, though his true plan is to flood the world and repopulate it with a new species of water-breathing men.
