He wants her to check a crime scene of a serial killer who was severely injured during an automobile accident while transporting bodies in 55-gallon drums. Her boss believes this is an open and shut case, but upon further investigation Watson realizes the serial killer had a partner. While working the case, she is activated in the Navy onboard the USS Vella Gulf.
