Geri’s life flashes before him in the “Buhera Matrix,” a cringe-worthy slideshow of childhood photos from Pioneer camp to prom night. He relives the absurd clash between Mickey Mouse and socialist youth rituals, debates the perfect horse-chestnut hole size and survives the notorious fruit-game initiation. As the disastrous graduation and its Bavarian-style sacrifices cap off his painfully vivid memories, the film spins forward through Hungary’s late-20th-and-early-21st-century history through the eyes of a ’70s-born generation.
