Summary

On a passenger ship to Japan, the journalist Kawase encounters a man who claims to be a Filipino, but Kawase believes he is a murder suspect who fled Japan fifteen years ago, Hojo Shuichi. To throw Kawase off, the man talks a female passenger, Reiko, into acting as if she was his long-time friend. When the man - who is, in fact, Hojo - secretly leaves the ship, Reiko, who has fallen for him, joins up with Kawase to go looking for him. Meanwhile, Hojo, who has returned to Japan to find the true murderer before the 15-year statute of limiitations on murder expires, tracks down the man whom he believes ordered the murder he was accused of.
