>> reporter: it was cold the night the full moon rose. february cold. in the desert valley that spilled down from reno, nevada.y and in that moonlight all silvee pale, the wind in the dead of in night worried that gray ends of winter grass, whipped and crieda up the driveway around the corner of the house, whistled he past the unlocked door. something evil afoot, something here inside. when the moon peered through the window and into the master bedroom, a little after 3:00 in the morning. >> it's really, really bad. >> what's really bad? >> my husband. >> reporter: strange, the things that happen to people under a full moon. good people, not so good people. under that moon that night it was hard to tell which was which, who was who.
