While working in a busy NHS hospital, nurse Tracy Pickford gets a better job in a private fertility clinic. The Jenner Clinic is out in the country, very quiet and far away from the bustle of the city. All seems normal, but for the off-limits section where they keep test animals, and the nightshift Tracy is assigned to would be boring except for mysterious activities centring on those out of bounds laboratories.
