S2, E5: While trying to help out Olive (guest star Caroline Neff) Voight (Jason Beghe) is attacked and taken. When he doesn’t show for work the team gets suspicious and begin investigating. Ruzek (Patrick Flueger) and Atwater (LaRoyce Hawkins) prove they do belong on the team when they demonstrate smarts and savvy tracking down a lead that will hopefully bring them to Voight. Meanwhile Burgess (Marina Squerciati) and Roman (Brian Geraghty) are trying to track down a girl who has run off with a police badge. Jon Seda, Jesse Lee Soffer, Sophia Bush, Elias Koteas and Amy Morton also star.
