The endearing and unflappable Dr. Annick Boudreau regularly confronts a myriad of mental health issues in her psychiatric practice at the West Coast Cognitive Behavioural Therapy Clinic. But even Annick is stunned when Sanjay, a young patient who suffers from Obsessive Compulsive Disorder, is arrested for the brutal murder of his roommate. While Sanjay is tortured by repeated violent thoughts, he is horrified by them and Annick is convinced that he would never enact one of them in real life. But the police and prosecutor are convinced that they have caught the perpetrator and aren't interested in looking very hard. Unable to talk to the authorities because of doctor-patient confidentiality, Annick feels compelled to investigate on her own, whatever the risks.
