Dan Brown’s The Lost Symbol (season 1)

As usual, the action takes place during one day, but this time in Washington. Langdon arrives in the capital at the request of his friend, who happens to be a 33rd degree Mason. That is to say, he is a very cool guy in the Masonic community. The professor is supposed to give a lecture at the Capitol. But instead he's running around town again looking for a lost symbol to save his kidnapped friend.
