When a naked, dead man is discovered in Doc Robbins' master bedroom by his wife, Judy, the crime scene evidence leads to one conclusion: she may have killed the man during a romantic tryst! Despite Mrs. Robbins' protests of innocence, the CSI's find it difficult to remain objective as the evidence against her mounts. The twisted tale leads to suspects related to the dead man's occupation as a genealogist, and his skill in finding familial links. Unfortunately for him, he uncovered one family secret too many.
