Alpha Kappa Omega Batch '81 (also known as Batch '81 or ΑΚΩ 81) is a 1982 Philippine dramatic film starring Mark Gil. Directed by Mike de Leon from a script by Clodualdo del Mundo, the film is about the titular fraternity's harsh initiation of a new batch of members in 1981 as seen from the eyes of Gil's character, Sid Lucero. It was screened at the 1982 Cannes Film Festival's Directors Fortnight. Although it is a joint production of LVN Pictures, MVP Pictures, and Sampaguita Pictures, the movie was also Sampaguita's last before it closed down.
Pour intégrer la fraternité étudiante philippine Alpha Kappa Omega, huit jeunes hommes doivent surmonter un rituel initiatique particulièrement violent qui s’étend sur plusieurs mois : humiliations en tous genres, actes de torture et bizutage quotidien.
