Synopsis

Nadia’s acquaintance guides the intelligence unit to a massive heroin seizure. The victory is shadowed, however, by Olinsky’s return home to discover the suspects have taken his wife hostage. Voight and the team believe they've identified a connection between the criminals and the drug operation, but their assumptions prove mistaken. Separately, Burgess and Roman are assigned a task that brings them together with Jenn Cassidy, a K-9 officer and Roman’s former partner and girlfriend.
