"My Strange Criminal Addiction" tells of compulsions that may be harmless but evolve into behavior more sinister and disturbing. From those of a lewd subway commuter to a diapered man, or a urine drinker to a toe sucker, firsthand accounts of people plunge viewers into scenes where disturbing actions take criminal turns. The real perpetrators -- some appear in disguise to conceal their identity, some speak from prison cells -- tell their stories. Dr. Mike Dow, a behavior specialist, explains how habits can turn uncontrollable and helps viewers understand the triggers.
