The Return of Atlantis

20 year-old Matthew Leverton survives a storm in the middle of the Atlantic Ocean, putting his father's death behind his back. He returns to Wales a few months later. Meanwhile his best friend June Calloway, who also happened to have graduated in the same University, was depressed that she couldn't see Matthew and was really worried. But she coincidentally bumped into him at a café seven months after the crash, and he offers her to accompany him to continue achieving his father's dream: finding the Lost City of Atlantis.
But will he make it in time before the team of destruction finds it, or will they win and Atlantis would be the last historical place in the world to be destroyed?
