Sonia (Regula Grauwiler) has had a bad time: Her marriage to the banker Frédéric Forster (David Rott), who comes from a good family, was more than disastrous, and her fear of him is still not over, even after the divorce. When she starts experiencing constant flashbacks, feeling colors and seeing sounds, after an involuntary LSD trip, she wants to go into hiding. 

Rather unexpectedly, she gets a job as a physiotherapist in a newly opened wellness hotel in Val Grisch in the Lower Engadine.
