Maria Enders (Juliette Binoche) is a famous international movie star and stage actress. She travels with a loyal young American assistant, Valentine (Kristen Stewart). She owes her career to having been cast, over 20 years earlier, in both the play and film versions of Maloja Snake by Wilhelm Melchior, a now elderly Swiss playwright. The play centers on the tempestuous relationship between a callous young girl ("Sigrid", a part that made then-18-year-old Maria famous) and a vulnerable older woman ("Helena") who is eventually driven to suicide after "Sigrid" takes advantage of her, squeezes everything she can out of her, then dumps her.
