Parangelia! (1980)

The Greek Junta, Athens, February 25, 1973. On a seemingly ordinary night, two brothers, former convict Nikos and his younger brother Dimos, visit a cheap nightclub with their girlfriends. However, instead of having fun, the siblings will find themselves trapped in a dangerous place filled with acrid cigarette smoke, decaying divas, and plain-clothes police officers. And as towering machismo and cynical provocations invite blind violence, a razor-sharp flick knife demands massacre in the grotesque shadows. But can blood appease pride?
