The BAU team is called in when a girl, Kate Joyce, is reported missing while vacation in Atlantic Beach.
Her roommates say she never returned to her hotel room after leaving the Sea-crets nightclub with two men, Syd Phillips and Jim Barrett.
The town and entire police force believe these two guys did something to Kim but the two guys aren't talking and it's been almost three days.
Only 12 hours are left before they're released.
Our team comes in to use their master profiling skills and observe the two guys' non-verbal cues to see if they can get something out of them.
Through their questioning and an important find by JJ, the team is able to create a more specific timeline that ultimately causes Jim Barrett to slip up.
In the final hour, the Coast Guard finds Kate, alive, clinging to a buoy, and reunites her with her family.
JJ can no longer ignore the repeated job offers from the Department of Defense and Director Strauss tells her she has no other choice but to leave the BAU and take the job with the DOD.
Hotch does his best to try and stop it and keep JJ but it's no use, and the team says goodbye.
