Lydia Kowalenko is fired from the pharmaceutical company where she has worked for many years because she refused to help cover up the use of a dangerous chemical. Her daughter Katja, however, has no scruples and risks an operation which is more beneficial to her own medical research than to the convalescence of a young patient. Then Katja's only son dies after a car accident. Was he too the victim of a career-minded doctor?
