When the little town of Ballymara's tourism is threatened by a cynical journalist, Moyra Rose O'Cullen challenges him. Tracing history back in time, she uncovers the roots of the local legend of the pledging stone at the door to the chapel and learns three stories of how her ancestors' bonds of love were formed over the ancient stone: Conn and Sorcha in 500 AD, Ardghal and Breanda in 1366, Nick and Keely in 1895. Can she convince the modern world that the legends are true? Will she form her own match over the stone?
