After Senate Majority Leader Lyndon Johnson loses the 1960 Democratic presidential nomination to Senator John F. Kennedy, he agrees to be his young rival's running mate. But once they win the election, despite his extensive legislative experience and shrewd political instincts, Johnson finds himself sidelined in the role of vice president. That all changes on Nov. 22, 1963, when Kennedy is assassinated and Johnson, with his devoted wife Lady Bird by his side, is suddenly thrust into the presidency.
