Reid is trying to decide where to take his mother for vacation, Garcia is excited by her upcoming trip to London to visit with Emily, and Rossi and Hayden, who have decided to rekindle their relationship, try to figure out how to tell Joy they are back together as a couple. This calm within the BAU is shattered when at Hotch's house, a SWAT team storms in taking him into custody, all done in front of a traumatized Jack, JJ and Henry. A confused Hotch, who is placed under the authority of the federal government, eventually learns that the Department of Justice (DoJ) has been monitoring him for weeks based on testimony by Peter Lewis - Mr. Scratch - who was apprehended by the BAU in a case last year, has evidence of his suspicious activities involving the making of a bomb, and felt the need to bring him in now based on a 911 call he made. Hotch knowing that he made no such call, the BAU team members come to the quick conclusion that Antonia Slade, the serial murderer involved in their most recent case, is involved in what is going on with Hotch based on the cryptic nature of the message of that 911 call. As the team tries to work its way through Antonia to the source of the plot targeting Hotch, Hotch himself tries to use his profiling skills in convincing the DoJ that he not only is not the bomber they believe he may be, but that he is better positioned to help them in the long run working with the rest of the team than he is behind bars. His profiling work may come back to haunt him in this regard. What is going on may end up being far bigger than any of them initially imagine...
