When two young girls are similarly murdered a little over a month apart, Detective Odafin Tutuola decides to investigate the gruesome crimes. After a third killing, Fin discovers that all three children were "anchor babies" of immigrant families, and reaches out to the Center of Immigrant Services. After sifting through the Center's hate mail, and witnessing a fight between immigration lawyer Randall Carver and Joe Thagard, a fanatical follower of a xenophobic talk show host, Fin begins to narrow in on the killer.
