Plot synopsis: In 1980, the capture of the infamous serial killer Pedro Alonso López, also known as the Monster or the Strangler of the Andes, seemed to end his nearly decade-long reign of terror. However, Ecuadorian laws benefited the murderer by giving him a shorter sentence and even the option of leaving in less time. When the Monster's release draws near, a group of family members struggle to find ways to keep him in jail, while he, from the inside, searches through a series of letters to clear his name and unmask the real killer: Jorge Patiño. The problem is that Jorge Patiño exists only in his mind.
