HBO will premiere the documentary The Final Year, about President Barack Obama’s foreign policy during the last year of his presidency, Monday, May 21.

The Final Year, directed by Greg Barker, “offers an insider’s look at key figures, including Secretary of State John Kerry, UN Ambassador Samantha Power, Deputy National Security Advisor Ben Rhodes and National Security Advisor Susan Rice, as they sought to promote diplomacy and redefine how the U.S. confronts questions of war and peace, all while preparing to hand over the machinery of American power to a new administration,” said HBO.
