Oscar's brother, who fought in WWII, died in battle under a cloud of suspicion. When the ship he served on is dry-docked, Oscar arranges for Jamie to join the salvage crew to search for any clue which might exonerate him. She finds one: the captain of the ship stole some money Oscar's brother had on him when he was killed, and hid it in the wreck for later retrieval. Jamie saves him, and one of her fellow dockworkers, from being deep-sixed by some thugs who plan to send the ship to the bottom again -- after collecting the money themselves.
