São Paulo

Sao Paulo is a city in Brazil.

Day 2
Nina Myers, who managed to have acquired information on the whereabouts of the nuclear bomb set to destroy Los Angeles from Mamud Rasheed Faheen, demanded a safe passage to the city, where she would then tell CTU the bomb's location. However, since her and Jack Bauer's flight was shot down, and Nina was forced to improvise, she did not go there. After she was released, it is unknown if she actually went to Sao Paulo.
