On an ordinary July morning, Rebecca Brandt, the owner of a beautiful house on the coast of Provence, decided that it was time to take her own life. Only the unexpected appearance in her house of tourists from Germany, the spouses Marius and Inga, kept the woman from the fatal step. However, during a boat trip on a yacht, Marius disappeared. Inga is desperate, but believes that everything is in order with her husband he will be found. The German police also hope for this: Marius is suspected of killing his adoptive parents, who horrified even those who saw the types of law enforcement officers with their cruelty.
