There are four envelopes, numbered 2, 3 and 4, each containing a date, time and map reference, unsigned and TARDIS blue. Who sent them? And who received the missing envelope numbered 1? This strange summons reunites the Doctor, Amy, Rory and River Song in the middle of the Utah desert and unveils a terrible secret the Doctor’s friends must never reveal to him. Placing his life entirely in their hands, the Doctor agrees to search for the recipient of the fourth envelope and figure out just who is Canton Everett Delaware the Third? Also what is the relevance of their only other clue: ‘Space 1969′? Their quest lands them—quite literally—in the Oval Office, where they are enlisted by President Nixon to assist enigmatic former-FBI agent Canton in saving a terrified little girl from a mysterious spaceman.
