Two police officers, Ciro and Freitas carry out a secret operation in Complexo do Alemão, under the command of Machado, eight years after the installation of the UPPs (permanent military police stations). They are told to capture Soldado, one of the principal criminal chiefs of the area, without conflict. In an unexpected turn of events, they are caught in an ambush set up by the rival criminal group. Meanwhile, police chief Amanda tries to send a rescue group, but faces equally challenging corporative problems.
