After meeting in a church basement support group for survivors of victims killed in a mass shooting, Abigail and Ben get drinks and follow their mutual attraction into a motel room and a romantic relationship. Ben doesn't know that Abigail is the mother of the shooter who killed his wife.

Ben tells his doting sister Jamie about having a new person in his life, and maintains his ties to his emotionally stunted brother-in-law, Sam. Abigail reveals to her ex-husband Ted that she is involved in a relationship, and with whom. Ted is furious over her indiscretion and tells her to break it off. Ben becomes embroiled in a feud with Brian Shaw, a right-wing radio shock jock with a penchant for rousing his millions of followers, and targets Ben.
