Obsession: Dark Desires

Boston-based private investigator Brian Wolfe is followed as he works on his cases. It's inspired by actual cases investigated by Wolfe and his assistant, Janine McCarthy, and whether the target is a cheating spouse, dishonest employee, or scammer, each half-hour episode follows the two from the initial client consultation to evidence-gathering stages and finally a confrontation with the accused. Wolfe, a no-nonsense guy with a thick Boston brogue, conducts field work using an arsenal of tried-and-true P.I. tricks; McCarthy picks up the data trail left on the Internet; and re-enactments give each case life, disclosing a shadowy world where things aren't always as they seem.
