Following a death of an immigration agent at a car wash where an undocumented immigrant (and a friend of Pete's) work, the Squad finds a cop involved in the illegal entry of Mexican youths across the border - all tied to a village in Sonora. The officer and Greer are at odds on how to handle the case.

The Squad investigates a unique nuisance racket headed by a man who turns out to be a close friend of Greer's.
