The true story of British intelligence whistleblower Katharine Gun who—prior to the 2003 Iraq invasion—leaked a top-secret NSA memo exposing a joint US-UK illegal spying operation against members of the UN Security Council. The memo proposed blackmailing member states into voting for war.
Unfortunately the movie Official Secrets is not yet available on HBO Max.
