When Elizabeth and Jack settle in to binge watch their favorite schlocky tv series - Into the Secrets Uncovered - they expect to see a Muppety chupacabra and a very iffy reenactment of Aztec death rituals. What they don't expect is that this week's guest has a photo of one of the Council's time travel watches and claims his slightly-unhinged grandfather traveled through time. Tasked with retrieving the watch, Simon, Elizabeth, and Jack travel back to 1956 Los Angeles and find themselves caught in a tangled web of Cold War espionage and kooky UFO conspiracy theorists. Desperate to keep the watch out of the government's - any government's - hands, they race Russian spies, the CIA, and even the Men in Black to get to the watch first.
