| The physician Dr. Katrin Herz needs support in her practice in Tangermünde. She finds it in the young Dr. Holly Sass. The Berlin city plant only agrees to the job on the Elbe in order to follow a promising lead to her missing mother. Dr. Katrin Herz puts her in touch with the previous practice owner, who probably knew Holly's mother as a patient. |
