From: Photo Flash: First Look at Series Premiere of DO NO HARM

On the pilot episode of DO NO HARM, set to air next Thursday, Jan. 31, renowned neurosurgeon Dr. Jason Cole (Steven Pasquale) has it all - including a dark secret. Every night at 8:25pm, Jason's body is overtaken by a dangerous alternate personality who goes by the name 'Ian Price' (also Steven Pasquale). For years, Jason has been able to restrain Ian with the help of an intense pharmaceutical cocktail - that is, until today. Now Ian is free and hell-bent on seeking revenge, which could jeopardize Jason's life, career, and budding romance with Dr. Lena Solis (Alana De La Garza). DO NO HARM kicks off its first season on Jan. 31 at 10 PM on NBC.
