Nolan is at a courthouse testifying over a DUI incident with Wesley Evers serving as the defense attorney. During the trial, every cellphone is interrupted with an alert that says that a nuclear missile is going to hit Los Angeles in thirty minutes. Nolan discovers a fallout shelter is under the courthouse but when he goes, he discovers the Judge has planned to leave them all behind as well as lock the others out.
Meanwhile, Lopez and West deal with a suicidal quartet of teenage girls who believe the missile is a cover for a space ship to take them to Heaven. Bradford and Chen attempt to deal with looting as order breaks down throughout the story. Harper, meanwhile, takes her daughter from school to make sure she's not with strangers if the world ends.
Nolan ends up thwarting a murderer in the bomb shelter with Evers help but the latter is (non-fatally) stabbed.
