Ghya Chang Fou is a 2017 Bengali underground film directed by Joyraj Bhattacharya in which thirteen unnamed Marxist revolutionaries gather in an archaic mansion to celebrate a communist revolution, but as the night progresses, drunken debates about communism and ideology slowly dissolve into complete chaos — with the gathering descending into violence, graphic sex, incest, and BDSM as the thin veneer of political seriousness gives way to raw human depravity and bourgeois decadence, exposing the deep hypocrisy between revolutionary ideals and the people who claim to hold them.
