Elise Andrioli was the victim of a terrorist attack, and now she is confined to a wheelchair, deprived of sight and speech, and communicates with others using notes that she writes blindly with her healthy left hand. Uncle Elise invites her, along with her faithful nurse Yvette, to his home in Castaing, a small village in the mountains famous for its ski resort. However, for Elise, this piece of paradise turns into a living hell. Soon after her arrival, a brutal murder occurs in the town, and someone begins to explicitly threaten Elise herself.
