In a world where memories can be mapped and emotions calibrated, trust becomes the ultimate currency. But when the lines between therapist, machine, and friend are blurred, who can you really trust? Dr. Emilia Bennett, a brilliant psychologist at Harmony Health Solutions, works alongside Echo, an advanced AI designed for the greater good. Together, they embark on a journey to revolutionize mental health therapy, treating patients with an innovative combination of human intuition and machine precision.
