Wojo brings in a sick perpetrator who collapses on the floor. The entire precinct is placed under quarantine, including a prostitute who gets friendly with Fish, Marty, Mr Driscoll, and Inspector Luger.
The entire 12th Precinct is under quarantine for the night, including the civilians, due to the threat of smallpox. Being cooped up in the same room together with no air conditioning starts to affect the men negatively. It gets worse when they overhear Harris' very vocal dreams where he seems to have a problem with everyone. The rest of the men share personal stories and conversations while waiting to hear from the medical lab if the pox is smallpox or just chicken pox.
It's Election Day. A woman, being prevented by her husband from voting, throws a toilet seat into the street to get attention. A shoplifter is escorted to vote by Wojo and then lost by him. Inspector Luger campaigns for a political crony.
Fish goes undercover to catch a mugger who's targeting Santas. Wojo doesn't know how to tell Yemana that his Christmas Eve date is a call girl. Luger fishes for an Christmas Day invitation from Barney.
