When a Navy sailor is found dead, the team tracks the suspicious movements of people in his life prior to his death. Also, Hannah comes to terms with her daughter's relationship with her ex's new girlfriend, Veronica.

The team investigates the death of a Naval microbiologist whose hobby as a "myth buster" resulted in his death at the hands of a legendary bayou creature. Also, Agent Khoury conducts an investigation into previous actions of Deputy Director Van Cleef, who recently demoted her for misguided allegations that she exhibited poor judgment.
