Premise: The old saying ``Nothing good happens after midnight'' rings true in the nonfiction series ``Nightwatch.'' Hourlong episodes follow emergency responders in New Orleans and Tampa, Fla., who work the busy, unpredictable 8 p.m. to 4 a.m. shift, battling time and circumstances while attempting to save lives. Responding to as many as a thousand calls a night are police officers, firefighters and EMTs who exhibit the skills, dedication and determination needed to properly serve their cities. Dick Wolf (``Chicago Fire,'' ``Chicago PD'') co-executive produces the series.
