A hit song during the 1930s, recorded most famously by Billie Holiday, the evocative "Gloomy Sunday" was notorious for allegedly driving people to suicide. Now it's the inspiration for this marvelous film, a love story with a twist. Gloomy Sunday flashes back from the 1990s to the early 1930s in the lush and romantic city of Budapest, where three people are caught in a love triangle.
