She is small, but dangerous. Wherever Benni (Helena Zengel) ends up, she is immediately expelled. The wild 9-year-old girl has already become what child protection services call a "system crasher". And she is certainly not looking to change her ways. Because Benni has one single goal: to be back at home with her mommy. But Bianca (Lisa Hagmeister) is scared of her own daughter. Mrs. Bafané (Gabriela Maria Schmeide) from child protection services is trying her best to find a permanent placement for Benni. She hires the anger management trainer Micha (Albrecht Schuch) as Benni's school escort and suddenly there is a seed of hope. Will Micha be able to succeed where all others despaired?
