Maurya has lost her husband, father-in-law, and five sons to the sea. As the play begins Nora and Cathleen receive word that a body that may be their brother Michael has washed up on shore in Donegal, far to the north. Bartley is planning to sail to Connemara to sell a horse, and ignores Maurya's pleas to stay. As he leaves, he leaves gracefully. Maurya predicts that by nightfall she will have no living sons, and her daughters chide her for sending Bartley off with an ill word. Maurya goes after Bartley to bless his voyage, and Nora and Cathleen receive clothing from the drowned corpse that confirms it as their brother. Maurya returns home claiming to have seen the ghost of Michael riding behind Bartley and begins lamenting the loss of the men in her family to the sea, after which some villagers bring in the corpse of Bartley, who has fallen off his horse into the sea and drowned.
