After four people, including tourists, are shot dead on the same sidewalk, Detectives Fontana and Green learn that one was a philandering jeweler with criminal ties to the Russian mob who was cooperating with federal authorities, until someone close to the victim "ratted him out." In the meantime, the investigators find the hitmen, but EADA McCoy must wrestle with the federal prosecutor over jurisdiction; and both cases might hinge on the fact that the jeweler was an Orthodox Jew.

When a convicted child murderer (David Groh) is struck and left for dead by a motorist just weeks after his prison release, Detectives Fontana and Green are not enthused about finding out who ran him over. When the murderer dies, they look inside the prison where he served his sentence, and they find evidence that leads EADA Jack McCoy to make a startling discovery.
