Martha Klein (MARTINA GEDECK) is the head chef at Lido, a chic German restaurant. Noted as much for her confrontational encounters with complaining customers as she is for her great dishes, Martha lives by herself and regularly sees a therapist (AUGUST ZIRNER) about her state of mind.
Her life changes when her sister is killed in an accident, essentially leaving that woman's eight-year-old daughter, Lina (MAXIME FOERSTE), orphaned. When the girl recovers from her injuries, Martha informs her of the bad news regarding her mother as well as the fact that Lina will have to come and live with her. Lina isn't happy about this, and wonders about her biological father, Giuseppe Lorenzo (DIEGO RIBON), an Italian man who's been out of the picture and whose whereabouts are unknown.
Not sure of how to raise a young girl and balance that with working, Martha asks her new downstairs neighbor, Sam (ULRICH THOMSEN), for help, and tries to figure out how to make the girl happy and/or eat. With Martha distracted at work and one of the cooks, Lea (KATJA STUDT), ready to have her baby at any moment, their boss, Frida (SIBYLLE CANONICA), has brought in Italian chef Mario (SERGIO CASTELLITTO) to help out.
Martha is furious since it's her kitchen and sees the jovial Mario not only as her competition, but also as her possible replacement. As the two try to get along in the kitchen, Martha tries to figure out what to do with Lina while searching for Giuseppe. By bringing the girl to work, Martha then sets into motion a series of events that will change her life forever.
