Part 1 Goliath Awaits : Season 1 Episode 1

Peter Cabot intends to salvage valuable treasures from the ocean liner Goliath, which was sunk by a German U-boat during World War II. Descending into the ocean depths, Cabot stares into one of the portholes of the Goliath only to see a girl staring back at him. Through luck and ingenuity, Goliath's air supply has been recycled for nearly forty years allowing a group of survivors and their progeny to live in a seemingly idyllic society ruled by benevolent despot John McKenzie who was the only surviving engineer from when the Goliath was sunk.
