The BAU is called to the Los Angeles area as three men were found dead in a lifeguard station closed for the season. Two were wrapped in plastic. All died a from a single gunshot wound to the head and were castrated postmortem. All three were not local, and had differing physical characteristics, differing socioeconomic backgrounds and differing sexual orientations. Other aspects of the deaths indicate that the unsub knew his victims. As subsequent victims emerge, the team learns that all were going through some sort of personal loss, which is why they were targeted since the unsub too probably experienced that same loss. The victims' missing vehicles, a female victim whose method of death was dissimilar to the males, toxicology reports and pin-pointing the common loss between all bring the team closer to finding the unsub, and who his ultimate targets are. Meanwhile, Rossi vows to complete this investigation by week's end so that Hotch can go on his first date since Haley's death.
