Chris Ryan travels to Rio de Janeiro in Brazil where he spends a week training with and operating alongside BOPE, the Special Police Operations Battalion of Rio's military police. The squad's specialty is crime fighting in the city's slums or favelas where they have to face armed and drugged up gangs of youths who protect a vast drug dealing network. Chris Ryan trains with the squad, learning techniques for fighting in the favelas before accompanying them on a real mission to confront a drug gang holed up in one of the city's largest favelas. After a dramatic shootout in the streets of the favela, the BOPE unit succeeds in dispersing the drug gang and disrupting their drug dealing activities.
