Designated Survivor (season 1)

Tom Kirkman is a mid-ranking official working as the secretary of housing construction and municipal development of the USA. In his contract, there is a clause which says that, in the case of force majeure, he is able to pretend to be the president. This clause seemed to be so insignificant for Tom, but something terrible has happened. A horrific bomb attack took place in the Congress during the annual appeal of the president of the USA.
