It is Senior Sergeant Gordon 'Laney' Lane's last day at work before retirement. He has had a full life of watching changes occur with not only the police department, but in his life; not all of which are good. He is walking the beat he used to walk, back in the day when cops used to 'walk the beat,' in the rain, remembering his life to that point.
'Laney' has an appointment. An appointment which, to him, will right a wrong; a serious wrong. He will avenge a life lost too young, that must be done, on this his last day.
