This episode concerns an RSPCA officer played by Michael Kitchen who is horrified to learn that a small pet shop has been buying wolves and experimenting on them.
The shop owner, Leo Raymount (Patrick Magee) has been trying to find proof of lycanthropy. This is a slowly built and very tense episode which really comes to a great climax and makes one think.
Nigel Kneal developed this program and wrote it as well. I'm glad Sinister is slowly bringing these out, and if you're a fan of well done British horror then I suggest you check this out.
