On Christmas Eve the Dankos invite Lt. Ryker over for dinner and ask him to dress up as Santa Claus to cheer up their niece whose parents are separated. Officers Webster and Owens maintain the Christmas spirit while out on patrol.
It's a "blue" Christmas when Jill's separated sister visits, her niece wonders if Christmas can even come without her dad. Police calls for Chris and Terry include a drunk driver, a stripper who doesn't want to perform her act on Christmas, a lonely old woman, a scheming peeping tom, a priest murdered by a crazy man, and a man who just lost job.
