Cousins Romy and Sasha grew up together just like sisters with their single moms in Berlin in the late 1980s. Today it’s Sasha’s birthday and their grandmother Hanne ends up in hospital with a two per mille BAC. As always, Romy tries to keep Hanne’s escapades a secret from the two mothers who throw a party for Sasha, with music and hamburgers and party decorations. While Sasha dances with her mother and aunt, Romy just stands on the sidelines. Sometimes you notice in less than a day that you’re no longer the person you pretend to be.
