The BAU is called in by the Center for Disease Control in an expected case of bio-terrorism in Arlington, Virginia, where two people, over the span of twenty-four hours, spontaneously bled to death, the symptoms mirroring the effects of Ebola. The two victims, a divorced female commercial loans officer at a bank and a married male civilian analyst for the Defense Intelligence Agency, had peripheral contact with each other which could be the connection in this case. The M.E. determines that the substance with which they are dealing is easily obtained rat poison, meaning that there is probably only one unsub instead of a terrorist organization at play. With a subsequent target, the unit is able to determine that the unsub is targeting the Arlington business community, the analyst the outlier among the victims. They believe the bank is the key to the unsub's rage. Food as a method of attack is important, but it also means that the unsub could easily poison mass amounts of food at a number of targets and locations. In addition to Reid who is still on a mandatory sabbatical, the team is also down Garcia for this case, she, who will be working remotely when she can, for the first time attending the parole board hearing for Jesse Wilson at San Quentin, he the drunk driver who killed her mother and stepfather twenty years ago. Of Garcia's many stepbrothers, only the youngest, Carlos Garcia, will be attending the hearing, he who will making a victim impact statement on behalf of the entire family, all who are determined to see Wilson remain behind bars for the entire twenty-five years of his sentence. As Garcia deals with this personal issue, she struggles with the entire notion of the choices one makes in life, some bad which lead to tragic consequences like the death of her parents.
