Siobhan was a Belfast girl from a working class family who grew up to become a university professor and world-renowned authority on English and Irish literature having been diagnosed with terminal cancer and all but given up for lost. In February 2000 she embarked on a pilgrimage to Lourdes after which her cancer completely disappeared. Her prayer had been answered. And even though, seven years later the cancer returned, Siobhan was able to die peacefully with the knowledge that her time had come. Renowned journalist and broadcaster Derek Jameson, Siobhan's father-in-law, and his wife Ellen unfold the remarkable life of this child of the Troubles and the unwritten pact she reached beside the holy grotto at Lourdes.
