With war about to erupt, Taiwan is plunged into blackout and paralysis, while the wife of national security adviser Chang Shou-bai goes into labor with her life hanging by a thread. To break the deadlock, Japanese businessman Suguru Fujiwara sets out alone across the Miyako Strait, now a deadly corridor filled with underwater mines, vowing to uncover the terrifying truth behind the coming storm himself.
