Sofia Sivenius (Elena Leeve), a renowned geneticist, Hannu Sivenius (Taneli Mäkelä), Sofia's father, and Henri Vaartama (Willehard Korart), a young man, are the focus of Finnish drama about a modern research hospital. The events of the series originate from a car accident witnessed by Sofia in which Henri is injured. However, the patient is referred to a research hospital instead of a polio, and Sofia's father forbids her daughter from attending Henri's treatment. Sofia begins to investigate her father’s actions and work - and is soon in the midst of a long-kept secret.

Sofia tries to reach Henri so she can decide how to deal with her father’s secret. Hannu chooses Anneli Jaakkola, who is pregnant, to be a patient at the research hospital. Jaakkola's case forces Sofia to find out how far she herself is willing to stretch the rules to save an innocent life.
