The day-to-day life of two unwilling partners of the San Francisco Police Department, Officers Nick Barton and Ben Chandler. These two beat cops patrol the urban sprawl of downtown's 19th district, in cruiser No. 2. 19-2 is about the tensions and bonds that develop between two incompatible men of very different temperaments and life experiences. Over time, Nick and Ben's mistrust and antagonism for each other give way to moments of mutual respect and a wavering chance at a true partnership.
