This fine episode finds Halstead and the crew investigating a string of violent pharmacy robberies. In one particular case, the gang kills a pharmacist and a bystander pulls a weapon and joins the fray and goes after the robbery gang. He is shot, hospitalized, and in bad shape. He's a veteran and his army buddies are gathered at the hospital and talk to Halstead, telling him how the guy worked bomb disposal in the Middle East and was a fine soldier. It turns out that he was having personal, emotional, and financial problems and that he was a paid lookout for the robbery gang, but when the robbery turned violent, he broke ranks with the gang and went after the shooters. Halstead, who we know was a Ranger who also served overseas, tries to help the guy and his family. Halstead is conflicted and must decide what to do.
