The storyline of this episode may have been derived from events that occurred involving drug lord Frank Lucas, who, in the late 1960s to early 1970s, cut out the middle men in drug trafficking, and bought his product directly from his source in Southeast Asia. He also used the coffins of deceased Vietnam servicemen to transport the product back to America.
