To the captain's dismay, his son Ryan has left the Navy for Garth Davidson's private security company GD. Its yacht MV Sassy is involved in suspicious transport under diplomat Tagobe's inviolability cover in pirate-infested waters. During a diamonds shipping, only Davidson is believed to survive a pirate attack. The Hammersley crew, however, tracks down wounded Ryan, who confided only in the cook to be a secret service recruit and works out Davidson's dirty game, for which RO researches a dire motive.
