During Christmas week, Ross (George Clooney) again tries to extend a helping hand to surly homeless teenager Charlie (Kirsten Dunst); Doyle (Jorja Fox) comes to the aid of a battered wife (Gloria LeRoy); and a mangy orphaned dog is "adopted" by Greene (Anthony Edwards), who is under the impression that the mutt would make a good gift for his daughter, Rachel (Yvonne Zima). In another development, Greene and Weaver (Laura Innes) try to forge a policy regarding HIV-positive employees, an action which may force Jeanie (Gloria Reuben) out in the open. ~ Hal Erickson, Rovi
