At a time when the number of contamination is exploding in Europe, the director of the Charité suspends Maral for imposing the continuation of his therapeutic trial against the advice of his colleague. What's more, the experiment has had disastrous consequences for Piet, who is now in a coma. Determined to continue the research at home, the researcher puts herself in grave danger. Julia, who knows nothing about Maral's experiment, attempts a high-risk operation to save a pregnant woman whose health is threatened by micro-plastic contamination.
