The Pilgrim (S02E08)

When the adult daughter of a retired cop turns up missing, Detectives Goran (Vincent D'Onofrio) and Eames (Kathryn Erbe) stumble upon a related case with more ominous implications as their search for the victim's boyfriend leads them to a shipment of explosives destined for terrorists who are planning an attack. As the clock ticks down and they work their way through a link of suspects – including an American schoolteacher – the detectives team with federal authorities hoping to find all of the homicide bombers.
