Losers (2015)

Teenage Koko lives in a nondescript town in Southern Bulgaria. His parents moved to Greece where the wages are higher, leaving Koko alone to care for his grandmother, an elderly and unwieldy woman with Alzheimer's. Koko is in love with Elena, an aspiring singer who seems only to care about a famous rock band scheduled to pass through town. On the night of the big event, the social fabric of the teens' provincial lives is thrown into disarray, paving the way for new constellations.
