The discovery of a pregnant teenage girl's body while Mariska Hargitay is chasing down another suspect leads to quite an elaborate tale involving two wealthy families on the Upper East Side. It all starts when Christopher Meloni deduces that the dead girl went to a posh prep school.
The deceased had been going out with Patrick Flueger and when Medical Examiner Tamara Tunie runs a DNA test on the victim it comes back with some surprising results. Not that Flueger was the father, but that is not all the surprise in store for him.
Later on Flueger's father is killed as well and Helen Slater the mother of the deceased girl is arrested for the crime. Still not all the surprise left in this episode.
I agree that this is one of the craziest episodes that SVU in fact all the Law And Order franchise shows ever did. Not one the best, but definitely up there in the crazy department.
