Clara, a 65-year-old widow and retired music critic, was born into a wealthy and traditional family in Recife, Brazil. She is the last resident of the Aquarius, an original two-story building, built in the 1940s, in the upper-class, seaside Boa Viagem Avenue. All the neighboring apartments have already been acquired by a company which has other plans for that plot.
After a bloody invasion of the BOPE in the High-Security Penitentiary Bangu 1 in Rio de Janeiro to control a rebellion of interns, the Lieutenant-Colonel Roberto Nascimento and the second in command Captain André Matias are accused by the Human Right Aids member Diogo Fraga of execution of prisoners. Matias is transferred to the corrupted Military Police and Nascimento is exonerated from the BOPE by the Governor.
