Desperate to infiltrate Oolong Island following the events leading up to World War III, Checkmate has recruited the Outsiders to help gain entrance to the facility. But unknown to the joint field team, the Chinese forces in control of the island were prepared for their assault. And when Checkmate attempted to remotely access the computers on Oolong Island, it launched an attack on Checkmate's computer system. In order to prevent a breach, the computers had to be shut down... which cut off all contact between The Castle and the field team. Cut off from their headquarters, and hounded not only by Chag Tzu's mad science experiments, but also by members of the Chinese Great Ten, can the Outsiders and Checkmate still accomplish their mission? And if so, at what price?
