To keep her mom's homesickness and true identity under wraps, Targa signs on for a mysterious salvage dive in the Baltic Sea. Her plan to blend in with the rest of the crew is spoiled when she catches the eye of a handsome local. A freak accident and a strange connection to the ancient shipwreck below attract even more unwanted attention. With both her mom's secret-and her life-in danger, Targa must finally find the courage to unleash the currents surging deep within.
