Mickey Ray signs his family up for a ten-day Caribbean cruise in hopes of enjoying some much-needed rest and relaxation. However, just a few days into the voyage, chaos erupts when pirates descend onto the ship from a helicopter and seize control. Their demand: a ransom of one hundred million dollars from the CEO of one of the nation's largest banks in exchange for the safe return of his son- and daughter-in-law.
In response, James calls in the Mongoose team, who covertly board the ship in the middle of the night and blend in among the passengers and crew. Soon after, James and Mickey are approached by Elisabeth, a CIA operative who had been placed undercover on board after the agency received intelligence about a possible pirate attack.
When the pirates eventually escape with the hostages, the Mongoose team tracks them to uninhabited Caribbean islands and manages to rescue one of the captives-though the pirates slip through their grasp. With the help of Valerie A.I., the pirate leaders are later located in the ship's home port of Norfolk, Virginia. Determined to recover the ransom money-and hopefully the remaining hostage-James leads the team into one final operation.
With the help of the undercover CIA operative, some quick thinking, and Valerie A.I.'s precision, the team brings the pirates to justice in a tense, action-packed finale with a surprise twist.
