The Amazing Race - Season 13 Episode 10

The remaining teams set off from their Pit Stop in a public park in Moscow, Russia and receive a clue instructing them to travel a retired Russian nuclear submarine and find an actor that appeared in the film The Hunt for Red October. Upon completing this task, the teams receive a clue directing them to the Park Iskusstv, also known as the Graveyard of Fallen Monuments. Here, one member of each team takes part in a Roadblock that tests powers of observation. All teams complete the task, but one racer makes a critical error-- losing the bag containing his team's money and passports. This team struggles to remain in the race, begging for money, as the teams complete a Detour task involving Russia's public transportation. Ultimately, they are unable to recover from this blow and are eliminated in the field, never completing the Detour or reaching the Pit Stop.
