After a successful experiment on Algernon, a mouse whose level of intelligence thanks to that procedure dramatically increased, the scientists decided to go further - the next "guinea pig" is Charles, a mentally retarded young man. The experiment is again successful. But what happens after it?

Mika is the wife of celebrated pianist Andre Polonski and stepmother to his son, Guillaume, whose mother died in a car wreck on his sixth birthday. Their lives are interrupted by the unexpected arrival of Jeanne, a young woman who has learned that she was almost switched at birth with Guillaume whilst in hospital. Also a pianist, Jeanne harbors a suspicion that she may be Andre's daughter. Andre undertakes to continue her piano tuition, but, on entering the Polonski family, Jeanne begins to notice the icily controlled Mika behaving strangely. Her suspicions aroused, Jeanne begins the dangerous task of unraveling Mika's dark past of secrets and lies...
