Castle and Becket have finally gotten togather now she's suspended, but prefer to keep that secret for now. With unofficial help from their NYPD team, they work out Castle's deep throat Mr. Michael Smith's deal with killer Cole Maddox, who comes after Smith and the file stolen from Montgomery's home, and realize the spider in the web is none other then a presidential candidate, former New York A.D.A., now US senator William H. Bracken. Drastic options are considered.
