A British Indian Army colonel is blamed for giving orders that resulted in a massacre of his troops. Dishonourably discharged from the army he returns to London. His four sons, Rodney, a student at Oxford, Wyatt, a London barrister, Chris, an aviator and playboy, and Geoffrey, an attache at the British Embassy in Washington, rally round to support him. He tells them he is the victim of a conspiracy by an arms syndicate, before he is found dead, apparently having killed himself. John Ford directed this sprawling saga that treks from India to South America, London, Egypt and the USA as the young men seek to uncover the truth about their revered father.
