John "Falcon" Chapman is a United States Marine Corps veteran who suffers from posttraumatic stress disorder. After playing Russian roulette, he enters a convenience store moments before it is robbed. He demands one of the robbers shoot him, and when the man hesitates, Chapman grows impatient, disarms the robbers, and foils the robbery. When he meets with his sister Cindy, who has briefly returned to New York for a wedding, she chastises him for not taking his medication and explains that she is returning to Brazil, where she has been doing charity work for a non-profit organization. Chapman receives word from Manny Ridley, a fellow veteran and diplomat, that his sister has been severely beaten. Chapman immediately leaves for Brazil.
