S4, E9: The bodies of two Tijuana police officers are found in the back of a stolen pickup truck, and all the evidence points toward an FBI informant as the prime suspect. But with corruption among police officers in Tijuana extremely common, it's difficult for Brenda's squad to know whom to trust.
