December 1962, a small village near Bristol. Eric and Irene and Bill and Rita. Two young couples living next to each other, the first in a beautiful cottage - suitable for a newly appointed local doctor - the second in a run-down, perennially under-heated farm. Despite their apparent differences, the two women (both pregnant) strike an easy friendship - a connection that comes as a respite from the surprising tediousness of married life, with its unfulfilled expectations, growing resentments and the ghosts of a recent past. But as one of the coldest winters on record grips England in a never-ending frost and as the country is enveloped in a thick, soft, unmoving layer of snow, the two couples find themselves cut off from the rest of the world. And without the small distractions of daily existence, suddenly old tensions and shocking new discoveries threaten to change the course of their lives forever.
