Season 9: Episode 16 - Psych Out

Psych Out: ­When Navy reservist and psychologist, Robert Banks, is found hanging in his home, it appears to be more than just a suicide after the NCIS learn that the man was working on a highly-classified case for the Defense Department and someone on the inside was using subterfuge to slowly drive him insane. While Gibbs goes toe-to-toe with Dr. Samantha Ryan, the ambiguous director of PsyOps, who seems to know more than she’s letting on, the team tracks down Banks’ field operator, Brian Mitchell, who points them in the direction of a PsyOps lieutenant dismissed by Banks six months prior. The team links the lieutenant to Banks’ death, but realize that the man is being framed by another PsyOps liaison â€" Mitchell. In the end, Banks’ death was for far more personal reasons than they originally believed: Mitchell was obsessed with Banks’ teenage daughter and killed her father for her so she could receive his $4 million life insurance policy.
