Lenz is a daydreamer, charming, imaginative and radically incapable of making decisions. After a night of celebration he wakes up quite dishevelled next to Ira. Lenz is in love. Ira too. The summer of love begins: fooling around in the Berlin night, beer at the canal, conversations about sex and childhood. Everything is beautiful. Until Ira asks the one question that changes everything: "Do you want to have children at some point?" Lenz then does what he does best when things get complicated: He runs off. Stumbling aimlessly through the summer, he meets the heros of his daydreams, who constantly cross-examine his feelings. When Ira suddenly stands in front of him again in autumn, he has to face the inevitable.
