They are the Choirboys - the patrol squad of the LA Police attempting to stay sane in an insane world. The Choirboys are five sets of partners on the night-watch, all men of varying temperaments and backgrounds, but they are joined together by the job, and they have elected to spend their pre-dawn hours in MacArthur Park in relaxing drink and sex sessions they call 'choir practice'. This is the story of men endangered ultimately not by the violence of their jobs but by their choice of off-duty entertainment. Simultaneously darkly funny and terrifying, this is as chillingly authentic as only a veteran police officer could make it.
