Blood Oath is a 1990 Australian feature film, known in some countries as Prisoners of the Sun. The film is based on the real-life trial of Japanese soldiers for war crimes committed against Allied prisoners of war on the island of Ambon, in the Netherlands East Indies (Indonesia), such as the Laha massacre of 1942.

It was directed by Stephen Wallace and co-written by Denis Whitburn and Brian A. Williams. The cast included Bryan Brown, George Takei, Terry O'Quinn, John Bach, John Clarke, Deborah Kara Unger, John Polson, Nicholas Eadie, David Argue and Ray Barrett.

Blood Oath was notable as the first feature film for both Russell Crowe and Jason Donovan, in minor roles.

The film was nominated for several AFI Awards in 1990, including "Best Film". It won the AFI Awards for "Best Achievement in Sound" and "Best Achievement in Costume Design".

The island of Ambon in Indonesia, 1945. During the War, the number of Australian POWs on the island had dropped from 1100 to less than 300 due to abuses by their Japanese captors. Capt. Cooper is the chief prosecutor. In a mass grave, the bodies of 300 executed servicemen have been unearthed. Cooper assumes that the massacre was ordered by Baron Takahashi, Japanese commander on Ambon. But the one potential witness has gone mad and is due to be shipped back to Australia. No captured airmen were found alive on the island at all, not even the four-man crew of a reconnaissance plane shot down late in the War. Takahashi is returned to the island in the custody of an American officer, Maj. Beckett. But there is little evidence with which to prosecute the Baron. Cooper thinks he could make a case for the missing airmen if only their bodies could be located. And why does Maj. Beckett appear interested in not seeing Takahashi convicted? Cooper gets a break when Lt. Tanaka, a communications officer and a Christian, surrenders himself... Written by David Stanko

On an obscure Pacific Island just north of Australia, the Japanese Empire has operated a prisoner of war camp for Australian soldiers. At the close of World War II, the liberated POWs tell a gruesome tale of mass executions of over eight hundred persons as well as torture style killings of downed Australian airmen. In an attempt to bring those responsible to justice, the Australian Army establishes a War Crimes Tribunal to pass judgement on the Japanese men and officers who ran the Ambon camp. In an added twist, a high ranking Japanese admiral is implicated, and politics become involoved with justice as American authorities in Japan lobby for the Admiral's release.
