Where there's smoke, there's fire. 

On Wednesday's episode of Chicago P.D., the Intelligence Unit is tasked with investigating a terrorist task which begins at a street festival where Burgess (Marina Squerciati), Ruzek (Patrick John Flueger) and Atwater (LaRoyce Hawkins) are on the beat at a daytime street festival.

As seen in The Hollywood Reporter's exclusive first look, it doesn't take long for Burgess and Ruzek to get suspicious when two men park a mysterious van illegally at the festival. When they get closer to the van, they see smoke coming from the front. While Atwater tries to chase down the two men left the van, Burgess and Ruzek and a few other police officers are tasked with evacuating the area as quickly as humanly possible.

Are they able to get the area cleared in time before the explosion? Is Atwater able to catch the suspects?
