When the Ancient Militia, a group of heavily armed terrorists, takes over the cruise ship Double Sea, a counterstrike team is put together behind the scenes to save the hostages, all VIPs from the international business world. The team leader is Japo, an amnesiac former mercenary with a heroic yet tragic past. He tracks down six other highly talented misfits from academia, law enforcement, and Hell Island, a mercenary training community. As these members of the newly-formed Team Wild train and clash with each other, the terrorists release a deadly plague on the ship and execute passengers whose companies fail to please. They also have a penchant for setting off explosives on board, which hints at a deeper motive. Eventually, skullduggery gives way to all-out action as the Wild 7 storm the Double Sea on motorcycles in a desperate bid to save the hostages before the ship goes down with everyone on board.
