Heroes II: the Return is a 1991 Australian mini-series about Operation Rimau during World War II.
The true and tragic story of Operation Rimau, one of the most daring raids of WW2. In September 1944 Ivan Lyon and 22 Australian and British troops attempted to blow up Japanese ships in Singapore. Just 10 miles away from the target they are discovered and so begin a long and desperate bid to escape to Australia. The series shows how after the war it is revealled that 13 men were killed during the pursuit and that the remaining 10 were murdered by the Japanese in a war crime. Tragically this was covered up and their killers were never charged while the men themselves never received any honours for their heroism.
