On a fateful summer night in 1969, a tragic car accident on a small Massachusetts island irrevocably alters the course of American political history. Jason Clarke delivers a gripping performance as Senator Ted Kennedy, a man burdened by family legacy and presidential ambition, who finds his future hanging in the balance after the vehicle he is driving plunges off a bridge, resulting in the death of young campaign strategist Mary Jo Kopechne, played by Kate Mara. This tense political thriller, directed by John Curran, meticulously unravels the agonizing hours and days that follow, as Kennedy, aided by his loyal cousin and advisor Ed Helms and confidante Jim Gaffigan, grapples with shock, guilt, and the immense pressure from his inner circle led by his ailing father Bruce Dern. The film constructs a compelling portrait of a man caught between personal moral failure and the ruthless machinery of image management, exploring the calculated decisions and public relations maneuvers that sought to contain a scandal threatening to destroy a dynasty.
