context: Joe (Cage) is a professional freelance contract killer. He works strictly by the rules; He never socializes outside his work, he stays secluded in quiet spots, never meets his handlers and always leaves on time, leaving without a trace. He usually hires young pickpockets or small-time criminals as his local help, whom he usually murders after the end of the job to prevent any identification. He uses multiple aliases and also has middlemen between him and his handlers. He also carries a watch to perform a hit in specific time and correctly visualizes his every target.
  After completing a hit in Prague and killing his current help, Joe travels to Bangkok for an assignment to assassinate four people for notorious Bangkok crime boss Surat, whom he never meets. Joe occasionally provides insight via voiceover narration throughout the film. He hires a local pickpocket with simple English knowledge, Kong, as his go-between in Bangkok, a condition of the contract being that the gang will never meet Joe. Contracts from the Bangkok gangsters are passed to Kong one by one via a nightclub dancer, Aom. Joe's first execution in Bangkok is done on motorcycle; when the target car stops at a red light, Joe kills all the passengers with a machine pistol.
  Kong retrieves information about the second target, again via Aom, and the pair become friendlier with every contact. Before Joe executes his mission, Kong informs him of the target, Pramod Juntasa, another notorious gang lord and Surat's rival crime boss who acts as sex trafficker, buying young girls from impoverished parents and selling them after sex deals. Joe sneaks into the target's penthouse and drowns him in his pool. Unsatisfied with Kong's assistance, Joe contemplates killing him, but after a brief confrontation when Kong is ambushed by local gangsters regarding a briefcase containing information files of Surat's/Joe's targets, he instead decides to act as Kong's mentor and trains him for self-defense.
  Midway through the movie, Joe meets Fon, a deaf-mute pharmacist, with whom he becomes intrigued after a brief consultation. Joe later returns to the pharmacy to invite Fon out for dinner. Soon after Joe falls for Fon and meets her mother. The affair is cut short when he shoots and kills two assailants in Fon's presence. Blood splatters on Fon, and she runs off, trembling and traumatized by the violent deaths. Feeling betrayed, Fon cannot forgive Joe and ends their relationship.
  Before the third kill, the gang attempts to identify Joe, and he warns them off. For the third execution that takes place at the Damnoen Saduak market, Kong assists Joe. The kill does not go as planned, and the target nearly gets away but Joe manages to catch and assassinate him. Before beginning his last mission Joe visits Fon, presumably to say goodbye. She initially ignores him but as Joe begins to drive away she runs after his car.
  His fourth target is the Prime Minister of Thailand. Joe is about to make the kill when he has second thoughts, is spotted, and escapes through a panicking crowd. Meanwhile, the gang has abducted Aom and Kong with plans to execute them. Joe, now a target, is attacked at his house by four of Surat's henchmen. He uses explosives to take them out and is faced with the choice of rescuing Kong or leaving the country unharmed. Joe decides to rescue Kong, so he sets off to the gang's headquarters with one of the half-alive attackers.
  Joe goes to the gang's headquarters, kills most of the gang including Surat's underboss/bodyguard (who is blown into half by explosives), and saves Kong and Aom. The fearful gang leader flees to his car with three other accomplices. Joe spots him and shoots the gang members, then gets into the back seat with Surat. As the police arrive at the location, Joe realizes he has only one bullet. He puts his head adjacent to Surat's, puts the gun up to his temple and pulls the trigger, killing himself and Surat.
