When several people including some children die, Rogers calls Fontana and Green because she says that all of them died from the flu. And that they were supposedly vaccinated but they didn't get flu vaccine. They learn that someone is selling false flu vaccine. When they find the one selling the vaccine, new A.D.A. Alex Borgia joins them. Eventually they find the one who supplied the vaccine and they get trouble admitting the evidence because of an oversight. So Alex needs to find a way to convict the man.
