本尼是一个娇弱的女孩,有着不受约束的精力。她是个“系统破坏者”。这个术语用来描述那些违反每一条规则的儿童;那些拒绝接受任何形式的结构的儿童,以及那些逐渐从德国儿童和福利服务的裂缝中跌落的儿童。不管这个9岁的孩子被带到哪里,她都会在短时间内再次被解雇。这正是她所追求的,因为她所想要的就是能够再次和她母亲生活在一起,一个完全无法应付女儿不可估量的行为的女人。She is small, but dangerous. Wherever Benni 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 is scared of her own daughter. Mrs Bafané from child protection services is trying her best to find a permanent placement for Benni. She hires the anger management trainer Micha as Benni's school escort and suddenly there is a seed of hope. Will Micha be able to succeed where all others despaired?
