Fugitive hunters and immigration enforcement teams work four separate cases across the United States. Officer Ken and his team track a Salvadorian murder suspect and alleged MS-13 member to the streets of New Jersey. In Miami, a woman facing federal charges is released back into her community fitted with an ankle monitor while a judge weighs her case. Agents in Tucson move in on a Cuban businessman suspected of laundering money for a narcotics operation, and elsewhere the clock runs down on a Guatemalan man wanted for illegal entry. The film follows officers through stakeouts, vehicle stops, and interviews with suspects and their families, cutting between the paperwork side of immigration enforcement and the tense moments of an actual arrest. Rather than editorializing, it stays close to the officers' daily routine, letting each case play out from tip to custody. The result is a procedural look at how US border and immigration agencies chase down suspects wanted for crimes ranging from money laundering to violent gang activity.
