Law & Order: Criminal Intent Episode 3.18 Ill-Bred

WHEN VET GETS MURDERED, DETECTIVES USE HORSE SENSE TO PROBE CRIME DOWN ON THE FARM -- Bad-breeding and brooding on a tony horse farm result in a bloody murder of an attractive veteranarian who began to question curious drug use surrounding her equine patients -- but Detectives Goren (Vincent D'Onofrio) and Eames (Kathryn Erbe) lay their ears back when they uncover a barn full of sexually active stable mates who appear to be smuggling illegal drugs in their animals. Goren, in particular, seizes on the jealousy and class rivalries between the rich owners and the married couple who work for them.
