It is April 1945 when U-boat U-2072 heads out of Hamburg for the last time. In its hold, the torpedoes have been replaced by gold and Nazi loot. The destination is Argentina. On board, ruthless Kapitanleutnant Falk Friedrich has brought his fiancée, Kristin Dassmer.

The U-boat is attacked by American torpedo bombers off the Bahamas and sunk. Kristin finds herself in a lifeboat with three others including Bern Munkelt, the man she is to spend the rest of her life with. They are rescued by Danardo Rolle and taken to Little Toe Cay, a remote island where Kristin's adventures begin.

"Azure Sea Gold" is an adventure, a love story and the story of greed, jealousy and ruthless people as well as a family story centered around three generations of women and their loved ones.
