Elegant, outgoing, gracious and entering middle age, Saara, a Helsinki gynecologist, is very much like the fresh snow covering her city: it looks splendid, but you have no idea what it´s covering... In Saara´s case, her self-assured exterior conceals a viper´s nest of jealousy. Saara has discovered that her husband Leo is having an affair with young Tuuli, one of his students, who also 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. She even establishes a troubling intimacy, partly by accident, partly by design. Saara plays it by ear, now lying, now telling the truth; now manipulating, now abandoning herself to emotions she never experienced before. She creates an elaborate scenario, giving herself a false name to mislead Tuuli and a false lover to dupe her husband. Soon she is no longer able to control the avalanche she has unleashed. Saara, Tuuli, Leo, but also Leo´s sister and her husband are all sucked into the thundering inferno of jealousy and revenge that will leave them all scarred...
