Magda, who long ago abandoned her career for the sake of her family, lives in Podkowa Lesna, near Warsaw. One evening, she accidentally discovers the body of a murdered woman in a park. The deceased has a W-shaped pendant around her neck - identical to the one belonging to her long-lost friend, Weronika. In the background of the murder, there are famous names of a businessman and a candidate for senator. The official investigation is conducted by commissioner Jacek Sikora, Magda's former friend, once in love with her. Since his biggest challenge so far has been bicycle thieves, the corpse in the park is far beyond him. Magda, a compulsive crime fiction reader, begins her own investigation. On the trail of the murderer and unraveling the mystery, their paths will cross many times. A handsome veterinarian will also appear on the horizon.
