When a young woman's body is discovered inside of a horse, Hannibal suggests to Jack that Will be brought in to help crack this peculiar case. Will has seemingly cast aside his suspicions of Hannibal, resuming their doctor-patient relationship, but Alana remains skeptical regarding Will's true intentions and worries that Hannibal may still be in danger. The FBI questions the man they suspect to be the killer in their case, but lack of evidence forces them to let him go. Will and Hannibal race to guard the safety of a witness they believe is in jeopardy, but it might be Will's own judgment that is in peril.
