A lower-level cabinet member is suddenly appointed President of the United States after a catastrophic attack on the US Capitol during the State of the Union in the Designated Survivor: Season One DVD Box Set.

On the night of the State of the Union, an explosion claims the lives of the President and all members of the Cabinet except for Secretary of Housing and Urban Development Tom Kirkman, who had been named the designated survivor. Kirkman is immediately sworn in as President, unaware that the attack is only the beginning of what is to come.

Determination, family and patriotism, will it be enough to keep the free world going?
