When we go through something impossible, someone, or something, will help us, if we let them . . .

It is October 1966 and William Lavery is having the night of his life at his first black-tie do. But, as the evening unfolds, news hits of a landslide at a coal mine. It has buried a school: Aberfan.

William decides he must act, so he stands and volunteers to attend. It will be his first job as an embalmer, and it will be one he never forgets.

His work that night will force him to think about the little boy he was, and the losses he has worked so hard to forget. But compassion can have surprising consequences, because - as William discovers - giving so much to others can sometimes help us heal ourselves.
