Synopsis by Hal Erickson
East China Sea is a "life is cheap" melodrama in which the American characters are the least appealing. A sociopathic gangster offers to shepherd a Japanese boat crew to safety. What the crew doesn't know is that the gangster is leading them into a trap. The U.S. Air Force is on maneuvers, and the crook hopes to provide a target for American gunners. Just why he does this is made clear (though not abundantly so) within the storyline. East China Sea was originally shown under the title Higashi Shinakai.
