Loin Like a Hunting Flame - S1.E12

Near the University of Colorado at Boulder, a group of college-age students gather at a warehouse/techno night club. Art Nesbitt, a pharmacist, approaches a couple, Mel and Leslie. He opens his palm, revealing two capsules. Under the influence of the powerful drugs, the couple accompany Nesbitt to a small room. Nesbitt captures their lovemaking on videotape, then injects them with a lethal poison.
