In Chula Vista, California on a holiday long weekend, a dead body is found with the hands and face damaged to prevent identification. The authorities believe it is either one of two teen-aged girls, Katie Owen or Lindsey Vaughan. Both went to the movies together eighteen hours prior, but who have been missing ever since. The BAU also believe that the victim knew her murderer, hence the reason for the obliterated face and hands which will give the unsub extra time to escape capture. From a telephone call made just prior to the murder, the BAU have an identity of the dead girl and hope to find the other girl still alive. Profiling victimology, the BAU discover that one of the fathers of the missing girls is not who he appears to be on the surface. Following up on other leads, the BAU find another dead body - not one of the missing girls - which provides a clearer profile of the unsubs and thoughts of vigilante-ism.
