Afraid of losing her husband to a younger woman, Helsinki gynecologist Saara makes friends with her rival using a false identity. A dangerous psychological game of life and death ensues...
Elegant, outgoing, gracious and entering middle age, Saara has discovered her husband Leo is having an affair with Tuuli, one of his students, who works at a martial-arts studio. Intrigued, Saara tries to find out who this girl is, and unwittingly ends up joining Tuuli's self-defense group. Little by little, Saara slips into Tuuli's life, gaining her trust and friendship. Saara alternates between lying and telling the truth, manipulating others and giving in to her emotions. She creates a false identity to mislead Tuuli and a false lover to dupe her husband. Saara, Tuuli, Leo and his family, are all sucked into the thundering inferno of jealousy and revenge that will leave them all scarred.
