While in Japan with Lois Lane and the pair under guard by the Japanese military, Clark has been sneaking out at night as Superman to sabotage the Japanese naval fleet. The military, irate at the damage being caused, takes Lois hostage and posts a public notice of their intent to execute her if he commits any further acts of sabotage. After sinking yet another naval vessel, Superman discovers the notice and must act quickly before the Japanese can make good on their threat.
