Farm life in the Yorkshire Dales isn't easy at the best of times but things are exceptionally tough for Tom and Sue. Their eight-year-old son has leukaemia and the doctors aren't making headway. Meanwhile Catherine ten feels lonely and neglected; befriending Uma the first Hindu at the village school she takes her to the Moors. Something strange happens which Catherine interprets as a vision of the Virgin Mary and a sign her brother will be all right.
