HAPPY VALLEY

From the creator of "Last Tango in Halifax" comes this police drama starring Sarah Lancashire ("Coronation Street") as Yorkshire police sergeant Catherine Cawood, a strong-willed officer coping with the suicide of her daughter and struggling to raise the young son she left behind. When the man she blames for her daughter's death is paroled, Cawood embarks on a mission to bring him down, unaware that her target is plotting another heinous crime.
