Blood on the Sun is a 1945 American spy thriller film directed by Frank Lloyd and starring James Cagney, Sylvia Sidney and Porter Hall.

The Japanese secret police visit the newspaper's headquarters, demanding that editor Nick Condon disclose the source, to which he replies, "The American Press".

As the secret police, led by Captain Oshima, arrive, Condon hides the document in his bedroom, behind a portrait of Emperor Hirohito.

The Japanese police have fabricated a story about him having a drunken party the previous night and fixed his house to hide the damage, and the document is missing.

Suspecting that the other party consists of Japanese anti-war liberals interested in sneaking the document out of the country, Condon publicly announces his intention to return to the United States.

Armed with this knowledge, Condon confronts Iris, who confesses that, while she does work for Tanaka, in her heart she is loyal to Japan’s liberal fraction.

Evading the secret police tailing him, Condon meets Iris, who is accompanied by Prince Tatsugi, a liberal within the Japanese government who hates the right-wing militarists.
