The U.S. Marshals work to stay two steps ahead of Tate, even casting U.S. Marshal Annie Frost (Kelli Giddish) as a ploy to lure him in. The case brings up raw emotions for Daisy (Rose Rollins) while Luke (Jesse Metcalfe) is involved in an internal investigation that could potentially indict Jimmy (Cole Hauser) and Marco (Amaury Nolasco).
