"Mental" is a medical mystery drama featuring Dr. Jack Gallagher, a radically unorthodox psychiatrist who becomes Director of Mental Health Services at a Los Angeles hospital where he takes on patients battling unknown, misunderstood and often misdiagnosed psychiatric conditions. Gallagher delves inside their minds to gain a true understanding of who his patients are, allowing him to uncover what might be the key to their long-term recovery.

As seen through the eyes of doctors and patients who, as Jack points out, have more in common then they're willing to admit, "Mental" also tracks the romantic and personal relationships of the team of doctors and hospital staff who work closely together as they delve into the mysteries, oddities and wonders of the human brain.
