Their SOS ignored by a strange yacht in a storm, the Hardy Boys find a wallet alongside their speedboat, apparently dropped from a helicopter, containing two thousand dollars, and are launched into a mystery involving diverse clues. This includes finding out who kidnapped Jack Wayne and took his plane, and where the wailing siren is coming from.
