Parasite
performed by Soho Vamp

All unemployed, Ki-taek and his family take peculiar interest in the wealthy and glamorous Parks, as they ingratiate themselves into their lives and get entangled in an unexpected incident.

When the remains of a young woman are found buried in an apartment courtyard with a collar and leash, Detectives Benson and Stabler determine that the dead woman is Ava Parulis, a Romanian immigrant who was brought to the United States for an arranged marriage. They discover from Ava's estranged twin, Irina, that the dead woman had left her abusive husband, and made a habit of taking advantage of wealthy suitors.
