context: Fernando (GermÃ¡n Jaramillo) meets Alexis (Anderson Ballesteros), a handsome gay youth, at a party of one of his old friends and immediately falls for him. The two begin a relationship which, apart from the sex, consists mainly in Fernando telling Alexis how pastoral the city was when he left, while Alexis explains to Fernando the ins and outs of everyday robbery, violence, and shootings. Even though Fernando has come home to die, his sarcastic worldview is mellowed somewhat by his relationship with Alexis.
  He soon discovers that Alexis is a gang member and hitman (or sicario) himself, and that members of other gangs are after him. After several assassination attempts fail because of Alexis' skillful handling of his Beretta, he is finally killed by two boys on a motorcycle. Fernando is partly responsible for this, as Alexis' weapon has been lost before the murder due to Fernando's suicidal impulses.
  Fernando visits Alexis' mother and gives her some money, and then walks through the streets aimlessly when he encounters Wilmar (Juan David Restrepo), who bears a striking resemblance to Alexis, not only in his looks but in his entire manner.
  He invites Wilmar for lunch and the two begin an affair, rekindling the kind of relationship he had with Alexis. Wilmar is also a killer, but it is a shocking revelation to Fernando when he finds out that Wilmar is the one who shot Alexis. He vows to kill Wilmar, but then learns it was Alexis who started the violence by killing Wilmar's brother, calling for vengeance on him by Wilmar.
  When Wilmar goes to say goodbye to his mother before he and Fernando leave the country together, he is killed as well. Seeing that the vicious cycle of atrocities in MedellÃ­n denies happiness, Fernando presumably commits suicide, if the last scene is taken to hint at that.
