On a lunch hour in crowded Archer Plaza in Dallas, Texas, a sniper, firing twelve shots, manages to kill six people. The BAU has to figure out if it is a random attack, a targeted attack, a terrorist attack - homegrown or foreign - or even something related to the upcoming fiftieth anniversary of the shooting death of John F. Kennedy. The six unrelated victims were killed in different parts of the plaza, the remaining six bullets splattered elsewhere throughout the plaza, leading to the team initially believing that it was a random attack by someone who was a bad shooter. But the nature of the six killed leads them ultimately to believe that the sniper was indeed an excellent shot, with the six non-fatal bullets being red herrings. They have to look at the backgrounds of the six dead to see who was the intended target or targets. Reid is able to narrow the target list to three, and most likely no more than two, the remaining victims being collateral damage. When a second sniper shooting occurs at a gas station leaving three more dead, the theory that it was a targeted hit is strengthened based on the location of the shooter in relation to the station itself. They have to find a connection between whoever the target(s) in the first shooting to whoever the target(s) in the second shooting to at least find the unsub's motivation. Even if they are able to find the connection, discovering the identity of the actual sniper may be a little more difficult.

While fixing a burst water main, a city works crew digs up the back yard of the home of the Johnsons - father Charles, mother Tina, and their middle aged son Lyle - upon Tina's approval. The Johnsons have lived at the house for thirty-five years. The crew finds the skeletons of two human bodies buried in the yard. The BAU takes the three members of the Johnson family in for questioning, who they believe know something about the skeletons, primarily because Lyle ran when he saw the authorities at the house. While Hotch, JJ, Morgan, Rossi and Cruz question the Johnsons individually, Lyle initially comes across as the most guilty by his animosity, however the team eventually believes his attitude is more a facade hiding other issues. Charles also demonstrates a more reserved form of animosity, he being a history buff who continually implies how he and his family, as being black, have been persecuted, this situation being no different. The identification of the two bodies and of the others which are eventually found in the yard, in addition to what Reid and Blake are able to find in the Johnson house may piece the puzzle together. Meanwhile, JJ wants to divulge to the team the fact that she and Cruz have been on special assignment, against Cruz's wants.

The BAU heads to St. Louis, Missouri where ten year old Andrew Taffert has gone missing. The reason it is a BAU case is that the Tafferts - father Malcolm Taffert and mother Lida Taffert - had been receiving prank calls from someone with a childlike voice stating "I'm gonna get you", and that blood was splattered on their front door after Andy had gone missing. Reid notices that this case is much like a fifteen year old cold case that the BAU worked on where the parents in that situation received such prank calls prior to their son being abducted and eventually found dead. The father in that case, Richard Clayvin, was always considered a suspect. As such, Malcolm is initially considered a prime suspect, especially considering his over controlling temperament. The similarity between the two cases extends to the post-abduction prank calls with the voice changing its statement to, "Did you see what I did?". But as the investigation progresses, which includes re-interviewing Richard Clayvin, the team may have to find other similarities before they can identify the unsub.
