Russian Love Poem

When a multimillionaire with a sordid sex life is found bound and slain, Detectives Benson and Stabler try to penetrate a suspicious ring of soulless Russian immigrants whose fatalism and enigmatic cooperation leave them going in circles. As Detectives Munch and Cassidy run down other leads, one possible culprit is Katya, a beautiful, cunning and likely illegal Russian who included the victim among her many boyfriends -- that is, until one of her male admirers issues a curiously bogus confession.
