In "PERCEPTION", Eric McCormack plays Dr. Geoffrey Pierce, an eccentric neuroscientist who uses his unique outlook and expertise to help the federal government crack difficult cases. Pierce's intimate knowledge of human behavior and masterful understanding of the mind are matched by his equally odd and imaginative view of the world. Cook co-stars as FBI agent Kate Rossi, Pierce's former student and the person responsible for recruiting him to work for the government. Smith plays Max Lewicki, Pierce's teaching assistant who has spent nine years at college. Rowan is Natalie Vincent, Pierce's best friend and every bit his intellectual equal.
