The first third of the movie serves as a kind of long prologue, showing Perfidia at work with the rest of the French 75, including her lover, “Ghetto” Pat Calhoun (Leonardo DiCaprio). They issue threats, set off bombs, shoot guns and make declarations. During a takeover of an immigration detainment facility, Perfidia meets Col. Steven Lockjaw (Sean Penn), with whom she enters into a secret sexual relationship. When she’s later arrested after a botched bank robbery, she rats out several of the French 75 in exchange for Lockjaw’s protection and implied companionship.
