  1. "Affinity": This delicious period piece, based on Sarah Waters’ 1999 novel of the same name, is a women-in-prison movie with a gothic Victorian twist. Upper-class Margaret, mourning her father’s recent death and looking for diversion, goes to Millbank Prison as a “Lady Visitor” — presumably to improve the female convicts but really as a way to step outside her limited, conventional world. When she finds herself irresistibly drawn to Selina, an attractive young convict, Margaret’s do-gooding quickly falls by the wayside.
  2. "Affinity" is a short film, written by L. Ron Hubbard.
