Henry is an unsuccessful screenwriter, and just as unhappy going from one casual relationship to another. Out of the blue he gets a fantastic job offer to co-write the screenplay of a bestselling novel together with Katharina. She is not only the author of the novel, but Henry's ex-girlfriend and love of his life. He now has a second chance and things couldn't get better when an 8 year old girl, Magdalena, shows up at Henry's door and turns his life upside down. She's his daughter from a long-forgotten one night stand 8 years ago and her mother Charlotte, who's attending a court hearing in the US, insists Henry takes care of Magdalena until she returns. Henry is shocked and so is Tristan who thought for 8 years that he was Magdalena's biological father. Life will never be the same for any of them.
