The Unsound is a story of Dev Oberoi, who suffers from multiple organic psychotic disorder - a condition that makes his behavior extremely unpredictable and at times even violent. Amidst a failed marriage and an impending divorce, a young beautiful girl Simran is charmed by Dev's flattering ways. But you don't always get what you see. So while those who are close to him desert him, there are others who enter his life not knowing what lies ahead.
Ironically, amongst those who fall in the trap of Dev's seemingly normal attractive persona is his own psychiatrist - a beautiful woman named Joana. Their torrid one-night affair happens despite Joana's committed relationship with Dev's close friend Dr. Kshitij Saxena. Will she expose the deep dark secrets of Dev's violent past and present to give him a better future? And can she rescue herself from the demons of Dev's unsound mind?
