描述：　　One early morning in March 2015, the Danish police received a call from a nurse at Nykøbing Falster Hospital. She suspects her close colleague of deliberately killing patients and fears that it has just happened again. Soon a murder case unfolds like never seen before in Danish legal history. Several co-workers are now telling the police that they also suspect the nurse has poisoned patients, and some even tell that they have been walking around with this suspicion for several years. But why hasn't anyone responded? And where is the evidence?
