La virgen de los sicarios / Our Lady of the Assassins (2000)

The tempestuous love story between Fernando, an older man who has recently returned to his crime-ridden drug capitol hometown of Medellin, Colombia and the gun-happy 16-year-old assassin Alexis, who murders all too easily. When Alexis himself is fatally gunned down, grief-stricken Fernando hunts for his young lover's killer in the Medellin slums, but instead encounters Wilmar, who bears an uncanny resemblance to Alexis.
