A young baby, SeaWalker, is lost at sea in the Bermuda Triangle where he is rescued by a family of dolphins. Miraculously, they take him to the deepest part of the ocean where he metamorphizes into a new species of sea creature who is able to communicate telepathically with all the creatures of the sea, from the largest blue whales to the smallest crustaceans.

Born to bridge the two worlds above and below the ocean, SeaWalker not only survives the harsh ocean environment, but soon becomes the leader of his dolphin tribe. His epic journey not only takes him to the deepest depths of the sea but leads to incredible encounters with space aliens' sinister plans for all life on earth.
