The story reveals his inner motivations and ensuing actions. Returning from a business trip abroad, he meets a Philippine nurse traveling to Cork to take up an appointment. Some time later, when he is confined to hospital, they meet again. An extramarital relationship develops between them, leading to complicated worries for Luke. In time, he is swept away by forces outside of his conscious control.
