Chapel's CI leads the GTF to a major takedown of one of Javier's shipments. A truck was "painted" with the cocaine. Javier realizes he has a mole and tests his people. The CI gives Chapel a location of an even larger shipment, but it was a trap to out the mole.
Chapel has no use for his CI any more until he informs Chapel that Acosta has someone inside the department. He's not able to identify him though. Chapel takes eveyrone's phones and Ryan's unable to reach out to Acosta.
Chapel offers to protect Acosta's family if he turns himself in. He refuses.
The GTF finds the larger shipment. Ryan tries to sink the sub, but he's unsuccessful. Javier's in trouble. Daniel gets taken by someone at the end of the hour.
