Jenna Smith is the daughter of Alec and Andrea Smith. Alec and Andrea where high school sweethearts, well they appeared that way. But Andrea's sister Emily could just never keep herself out of it, until Andrea went missing. After the disappearance of Andrea and Alec Smith, Harvey, Jenna, and Mary-Beth are determined to find out what happened. But with all of them caught in web of lies and secrets, and Emily their new guardian who has just as much to do with it as anyone else, things are not as easy. And when all three are suspects for murder, things get shaken up for the Smiths.
its been 13 years sense we last saw the team. the only remaining members of the team left are JJ, Reid, Emily and Tara everyone else has moved on and kind of fallen out of touch with each other but all of that is about to change when Reid's 16 year old daughter is arrested after being found running from a murder scene covered in the victims(her best friends) blood, claiming to have no memory of what happened. the team decides they need to call back old member's of the BAU for one last case but the question remains did Jenna murder her best friend or is someone framing her?
