A car belonging to a businessman's associate has been stolen. However, the investigation becomes dire after Greer learns that that car was rigged with dynamite, as the businessman wanted to commit murder. The Squad rush to find the car before the dynamite explodes at 5 p.m., potentially killing an innocent family who rented it.

Greer and another veteran cop have both been frustrated by a drug pusher they've been trying to nail, who has twice had his case dismissed on legal technicalities. Finally, the third time appears to be the clincher, as the man is caught at an airport with a case full of heroin.
