After two dead bodies are found in an otherwise idyllic forest, an investigation by members of the NCIS team soon draws them into the strange and surprisingly wild world of modern-day treasure hunting in the new episode "Blood and Treasure." Elsewhere, Gibbs and Fornell (Mark Harmon, recurring guest star Joe Spano) make their way deeper into their own search for an opioid kingpin. Tom Wilson, Sheva Cohen and Anthony Konechny also guest star; Sean Murray and Emily Wickersham also star.
