When a federal judge is gunned down execution-style in broad daylight, the team is sent looking for a suspect with ties to a local Islamic center. Also, Maggie reunites with a former colleague while things become tense between OA and his girlfriend Gemma.

When a bombing at a local restaurant leaves several injured or dead, including a congresswoman and someone close to Isobel, the team races to apprehend the suspect before another explosive goes off.

The team is thrown into a highly political case after four members of the Taliban are shot and one is kidnapped in New York with no record of their entrance into the country. Having served in the U.S. Army, this case hits close to home for OA, who struggles to open up to Gemma about his past in Afghanistan.
