The BAU's next case takes them to Boulder City, Nevada, where a Jane Doe was found frozen to death - the natural elements in the area which would be unable to achieve that state - weighted down in Lake Mead, with J.J. noticing a electric shock burn mark above the breastbone which would have revived the victim as she froze to death. She is eventually identified as Sarah Rhodes of Kingman, Arizona, a mother of ten year old Bobby Rhodes, she who made regular ATM withdrawals of $260 every month near Boulder City. Examining Sarah's body and reviewing the ME report, J.J. is able to figure out that Sarah was a cult member, the near death to revival simulating a state of euphoria upon "rebirth". The team believes Bobby is still within the cult. They not only have to find the cult and its leader in order to find Bobby, but tie it and him to the deaths, which may be difficult to do unless they can find ex or current members willing to testify. Hotch and Rossi discover an unusual twist to the case once they locate the cult compound. Through the process, Reid notices that J.J. is going through something emotionally, probably having to do with it approaching the one year anniversary of her abduction and torture. But there are aspects of the case that bring those thoughts of one year ago to the forefront of her mind.
