Full Circle: Mexico/Western USA/Canada/Alaska - S4.E10

In Mexico City, Palin attends a lucha libre match and listens to a lively mariachi band. The next day, he observes the darker side of the city, as a graffiti protest is being led by a lucha libre wrestler named Super Barrio. On to a small village outside of Querétaro, he helps a lady make tortillas. He then catches a bus to the town of Tijuana, where after observing a house in the shape of a woman, he walks to the United States–Mexico border, a.k.a. the "Tortilla Curtain". Here he observes "Pollos" attempting to cross without any security noticing. Afterwards, Palin crosses the border legally into San Diego and gets a glimpse of the border from the American perspective. Venturing north to Los Angeles, he gets a bird's-eye view of the city from a local news helicopter reporter. He then becomes involved in a breaking story of a plane approaching Van Nuys Airport landing on the freeway. Driving along the California coast, he reaches San Francisco and the Golden Gate Bridge.
