The action takes place in Japan 50 years ago. Yori, a Japanese prince, picks up Allan Carroll, a shipwrecked American sailor, and hides him in his home, as it is a crime for foreigners, except the Dutch, to land on Nippon's shores. Iku, an enemy of Yori, is apprised of the presence of Carroll. He raids his enemy's palace, and makes prisoners of Carroll and Yori. Both are sentenced to die, but Carroll escapes after killing Iku. The action then jumps to the present day, and when Iku III, who comes to America to study its customs, learns that Allan Carroll III, is the man he wants, he seeks to avenge the death of his grandfather by taking Virginia Stanford, Carroll's fiancée, to Japan. Carroll follows. As a result of a fight between the American and the Japanese, Carroll kills Iku III, and returns to America with his sweetheart.
