For three years my younger brother was a student the famous Peruvian military academy, Colegio Militar Leoncio Prado. A secondary school with quite an illustrious history as well as several eye raising rumors (I will write a follow up article on the school later this week).
Mario Vargas Llosa, a famous Peruvian writer and controversial politician was not only the author of the popular book "Cuidad de los Perros (City of Dogs)" but is also an alumni of Leoncio Prado. It was in 1985 when film director Francisco J. Lombardi adapted Llosa's book onto film. The film centers around four cadets and their life within the walls of the infamous military academy. Within the walls of the academy exists a world hidden from the outside where the events led by films main characters lead to murder.
Luckily I have found the film on YouTube and have included it below, unfortunately the films are in Spanish but I still recommend it, Enjoy!
I like Llosa's essays and have read some of his fiction in the past. The movie sounds interesting. I'll see if I can find one with subtitles.
