Iniciamos con el chirrido de unos llaves, es un agente que entra al cuarto de interrogatorio para hablar con un sujeto que ha estado preso ya un tiempo, que aparentemente no le importa mucho lo que hizo y bromea con el agente hasta que le pasan un chicle de sandía pero no lo acepta porque no intercambiar información solo por un chicle ni porque es de sandía pero esto es el gente solo le resbala porque al leer el expediente le expresa que tiene unos cuantos años por delante preso pero al otro ni le importa y bromea pero de igual forma el agente le cuenta que no vino a pedirle permiso para llevárselo porque eso es lo que hará y parece ser su hada madrina pero no porque no irá de gratis sino porque trabajará para ellos, para la CIA, será un agente de un grupo de élite dispuesto a matar ya que conocen a los de su clase (acá quiero hacer un inciso, si es un reo, no tiene problemas con seguir preso, por que lo sacan a la fuerza?); Será parte de la zona gris y no tendrá días libres ni tiempo de salida pero para estar preso… ustedes me dirán.

18 años han pasado y ahora está en Bangkok, en un lugar ostentoso y fiestero que parece ser un club, allí se encuentra con una chica que le da un cumplido pero rápidamente el capta que aliada y ella le da una pistola de agua que el usa irse, ya que es la llave de un cuarto debajo de la pista de baile, allí está un arma de alto calibre esperándolo con un auricular para darle las instrucciones del otro lado del continente su jefe le dice que tiene que eliminar a alias "vagón comedor" que se encuentra comprometiendo información nacional secreta pero vagón comedor no llega solo, llega con muchos escoltas que al abrirse paso por el club. Acá nos enteramos que nuestro prota lo hacen llamar seis, exactamente sierra seis. Seis apunta directo al sospechoso pero detecta que un niño está cerca y se niega a hacer el disparo por daño colateral pero de igual forma le dicen que haga lo que sea necesario sin importar que ocurra y justo cuando va a efectuar el disparo, no lo hace y dice arma trabada, enfurece a los jefes pero no se queda ahí.

Sale del cuarto, activa la alarma de incendio que alerta al sospechoso y lo hace huir, mientras huye el va eliminando a sus guardaespaldas hasta que ya es evidente y busca la manera de eliminar al objetivo de cerca pero este escapa hasta caer en un lugar donde ya lo espera, seis al bajar es atacado por el sospechoso que no trata de oponer resistencia realmente, especialmente porque le dice que ha venido por uno de los suyos ya que él es sierra cuatro, le están mintiendo y él conoce la verdad pero esto a seis le resbala de nuevo y trata de aniquilarlo, pelean por varios minutos pero seis lo hiere de muerte; antes de morir el supuesto sierra cuatro le dice muchos secretos o cosas que un sierra podría saber y hace dudar un toque a seis y lo obliga a tomar un collar dorado que significa algo y le dice que mate al jefe que dejó furioso en la oficina anteriormente, muriendo… ahora seis deberá descubrir si lo que dice es cierto porque es lo que parece

We start with the squeaking of some keys, it is an agent who enters the interrogation room to talk to a guy who has been in prison for some time, who apparently does not care much about what he did and jokes with the agent until they pass him a watermelon gum but he does not accept it because he will not exchange information just for a gum or because it is watermelon but this is the people just slips him because when he reads the file he tells him that he has a few years ahead in prison but he does not care and jokes but the agent tells him that he did not come to ask permission to take him because that is what he will do and it seems to be his fairy godmother but not because he will not go for free but because he will work for them, For the CIA, he will be an agent of an elite group willing to kill because they know his kind (here I want to make a digression, if he is a prisoner, he has no problem with remaining in prison, why do they take him out by force? ); He will be part of the gray zone and will not have days off or time off, but to be in prison ... you tell me.

18 years have passed and now he is in Bangkok, in an ostentatious and partying place that seems to be a club, there he meets a girl who gives him a compliment but quickly he catches that ally and she gives him a water pistol that he uses to leave, since it is the key to a room under the dance floor, there is a high caliber gun waiting for him with an earpiece to give him instructions from the other side of the continent his boss tells him he has to eliminate alias "dining car" who is compromising secret national information but dining car doesn't arrive alone, he arrives with many escorts who as he makes his way through the club. Here we learn that our protagonist is called six, exactly sierra six. Six aims straight at the suspect but detects that a child is nearby and refuses to fire the shot because of collateral damage but is told to do whatever it takes no matter what and just as he is about to fire the shot, he doesn't and says gun jammed, infuriating the bosses but he doesn't stop there.

He leaves the room, activates the fire alarm that alerts the suspect and makes him flee, while he flees he eliminates his bodyguards until it is evident and looks for a way to eliminate the target closely but he escapes until he falls in a place where he is already waiting for him, six is attacked by the suspect who doesn't really try to resist, especially because he tells him that he has come for one of his own because he is sierra cuatro, they are lying to him and he knows the truth but this slips back to six and he tries to annihilate him, they fight for several minutes but six wounds him to death; before dying the supposed sierra four tells him many secrets or things that a sierra would know and makes seis hesitate a touch and forces him to take a golden necklace that means something and tells him to kill the boss that he left furious in the office before, dying.... now six must find out if what he says is true because it is what it seems.
