Series one In the autumn of 1956, Freddie Lyon (Ben Whishaw) is a reporter unhappy with his job producing newsreels for the BBC. Desperate to get onto television, which he feels offers greater immediacy, Freddie is unaware that his best friend Bel Rowley (Romola Garai) has been selected by their mentor Clarence Fendley (Anton Lesser) to produce a new news magazine, the eponymous "The Hour". Rowley selects experienced war correspondent Lix Storm (Anna Chancellor) to head the foreign desk for the programme, leaving Freddie to run domestic news, a position which he considers inferior. For anchor of the programme, Clarence selects the handsome and patrician Hector Madden (Dominic West). They are joined by Thomas Kish (Burn Gorman), a mysterious and taciturn translator for the BBC who helps them cover the developing Suez Crisis. As the team struggles to put the show together, Freddie is approached by Ruth Elms, the daughter of a member of the House of Lords who had employed Freddie's mother. She asks him to look into the murder of Peter Darrall (Jamie Parker), a college professor whom she knew. Soon after, Freddie finds her dead in her hotel room, an apparent suicide. As the Suez Crisis escalates, the production team strives to report on British involvement in the crisis, despite pressure from the administration and in particular Angus McCain (Julian Rhind-Tutt) to present a sanitised narrative for the public. Freddie becomes more and more convinced that Peter Darrall and Ruth Elms were killed for some sinister reason. He discovers a secret message that Darrall tried to pass on before he was murdered: "Revert to Brightstone" and finds a movie reel depicting Ruth, Darrall, and Thomas Kish on holiday together. When confronted, Kish intimates that the government is behind the murder of Darrall and Elms, but he kills himself after a struggle with Freddie before the latter can learn more. Bel begins an affair with Hector. Hector's wife, Marnie (Oona Castilla Chaplin) finds out, telling Bel that she wasn't the first woman to have been with him since they married. After Clarence tells Bel that the affair threatens to ruin her career and damage the show, she calls it off. As the Suez Crisis flares into armed conflict, Freddie learns that Darrall had been a communist spy and had been involved in a program to recruit bright and susceptible young people, referred to as "Bright Stones" to the
