Ten individuals come together to live out their spy fantasies and attempt to win a game of espionage, based on a WWII spy program. The competitors must infiltrate a black-tie gala and find a contact after spending 24 hours surviving in the woods.

Nine competitors race through a physically demanding course and put their training on lock-picking to the test; back at the safe house, suspicions run high over a stolen dossier.

Competitors break into two teams for a head-to-head challenge. Tasked with breaking into a spy safe house to gather intelligence, only one competitor is named the winner and another is dismissed.

Competitors are dropped from the side of a building, as the Assessors test their ability to retain and recall information while under extreme pressure and alliances in the house begin to turn against one contestant, who is dealt a sabotage.

The Assessors push the competitors past their physical and mental limits in an endurance test, and with the challenge taking a dangerous turn, the frontrunner cracks under the pressure.

The remaining competitors are given false identities and sent on a blind date. When the Assessors turn up the heat on the challenge, the contestants have to maintain their aliases.
