19-year-old Jakob lives in Cologne, sharing a flat with his brother and the latter's girlfriend, Karo, who is pregnant. He's a drifter and obsessively records his daily life on video. He films himself while masturbating, secretly observes his brother and Karo through the lens, and documents the concerts of Phillip, his friend. He gets drunk with Piet's mother, satisfies Mani on the riverbanks, scrounges money off pedestrians, breaks into a house, and together with Phillip smashes the furniture.
