Plot Summary:Ludo Decker and Anna Gotzlowski have been living together for two years. Everyday routine has set in, with Ludo neglecting his household responsibilities much to Anna's dislike, while he is in turn annoyed by her constant complaining. When Ludo runs into his former lover Marie in the disco, and Anna's old boyfriend Ralf comes to stay in their flat for a few days, the young couple faces serious jealousy and doubt in their relationship. Anna secretly reads Ludo's phone messages, while he in turn stumbles upon "The List", an account of Anna's former lovers-including Ralf, who scores better than Ludo does. After a number of provocations, Ludo beats Ralf in a restaurant, and angrily leaves Anna. Even though the two still strongly care for each other, they end up sleeping with their respective ex-lovers. Ralf confesses that he never stopped loving Anna, but she rejects him and tells Ludo what happened. Even though Ludo has cheated on her as well, he angrily argues that she herself told him that, unlike men, women do not actually sleep with someone without feelings being involved. Anna begs him to come home, but he only says that he has no home any more, and leaves. Meanwhile, Ludo's best friend Moritz desperately tries to get more successful with women, and ends up in a number of absurd situations. In the end, he meets a young and beautiful sex-addict named Lana. After a few weeks, Anna receives a letter from Ludo, who has traveled back to the place where they spent their first and only vacation together. He writes that he misses her terribly, and that he wants nothing more than to come back, have children, and spend the rest of his life with her. Anna follows him and finds him on a lonely beach, where she tells him that she wants a "little Ludo" before they can talk about a "little Anna". In the end, they return home together.
