Chicago PD: The team tries to keep a batch of high-calibre weapons off the streets.

SYNOPSIS

Voight and his team are left reeling in the wake of the death of the death of one of their own, so when an explosion is reported, the subsequent investigation provides them with a much-needed distraction. Two people were killed in the blast, which was caused by an IED, but the only credible witness to the incident is a young girl whose mother worries what co-operating with the police might mean for her daughter's safety. Meanwhile, Platt is furious to hear Chief Baumgartner is opposing her efforts to commemorate her fallen colleague. Crime drama, starring Jason Beghe.
