It will be based in one of Mexico’s small towns plagued by warfare between competing drug cartels and government’s armed forces. A serial killer, suspected to be affiliated with one of them, has gone on rampage by killing en masse dozens of teenage girls in a certain time period, inside their vicinity. They are slashed, mutilated, and some of their body parts are even displayed across the routes (a common tradition of show-off by cartel leaders to terrorize the populace). Many of their parents, and in particular their teachers, are psychologically affected by such gory happenings. Hampered by weak legal enforcement, some of them even attempt to avenge their beloved ones’ deaths by putting an eye to an eye towards the cartel leaders.
It is not until a psychiatrist, and a teacher, confront them, and tell them the complicating, intricately interconnected nature of these organizations, and how their blatant, ill-considerate revenge may disrupt the stability of the entire community.
Note: La Matanza is Spanish translation for ‘bloodshed’.
