When Agent Mick Francis takes command of a mass murder case named The Nation's Murder that flares up through the United States, only to find that he has to deal with the realization that his deceased wife might be the one behind the whole plan to balance the insurance company's earnings by having the elder members taken out of the equation. Agent Francis leads a team of 32 agents in 17 states to try to solve this mass murder case that spreads through the country. As Mick goes back to his home state of New Jersey, he finds that the government ran insurance company that his deceased wife used to work for has been hiring ex-military personnel from a group named H.E.R.O. to carry out their mission to get rid of their elderly members to save the company money. Mick deals with all the attempts against his life, a brand new partner, his new love interest Mia Sanchez the forensic pathologist, and his dead wife Beth that might have taken on a new persona and really might be alive. He finds himself not knowing who to trust when everyone around him gives him a reason not to trust them.
