Designated Survivor is an American political drama television series. A low-level Cabinet member becomes President of the United States after a catastrophic attack kills everyone above him in the Presidential line of succession.
On the night of the State of the Union address, an explosion claims the lives of the President and all members of his Cabinet except for U.S. Secretary of Housing and Urban Development Tom Kirkman, who has been named the designated survivor. Kirkman is immediately sworn in as President, unaware that the attack is just the beginning of what is to come. Kirkman must struggle to keep the country and his own family from falling apart, while navigating the highly-volatile political arena and while leading the search to find who is responsible for the attack.
