Among the simple fisher-folk of a little island off the west coast of Scotland lives MacTavish, head of a clan. Here he rules as a chieftain and his word is law. One day a hurricane sweeps across the Hebrides and the fishermen turn their boats to the inlet for shelter. On the shore the women and children watch the fight of their men with the waves. Among those who wait is Margaret MacTavish, who sees her father's boat dashed to pieces in the roaring surf. A party of men headed by Jamie Campbell, try to rescue the old chieftain but the waves close over him before they can reach the battling craft. With MacTavish lost, according to the law of the island the succession of authority passes to his daughter Marget, just eighteen. She, with a spirit of kindness and in a tender, sweet and girlish way, rules the fishermen and their families. Her disposition wins them. Jamie Campbell, a young fisherman, has won Marget's heart, Jamie has always been regarded as the son of Mrs. Campbell, one of the clan. The old lady realizing that Jamie is reaching his twenty-first birthday feels that she cannot keep her secret longer. So she writes to the Countess of Dunstable that the baby of her first marriage, which she left with the old woman of the island, did not die but had grown to be a fine young man, and is now known as Jamie Campbell. The Countess accompanied by her husband starts out to seek her son. It is on the eve of Jamie's betrothal to Marget that, the Countess finds the young man and tells him of his real identity. She swears him to secrecy even from his own sweetheart. The Countess goes to watch the quaint betrothal ceremony of her son and Marget. Meeting him they are seen by those who do not know the relation to embrace and this fact is told to Marget. The disappearance of the Countess has aroused the suspicions of the Earl, and he, having learned of her secret meeting with, Jamie and not knowing the relation, confronts her. The wife breaks down and confesses that the young man is her son. There having been no children by the second marriage the Earl is delighted with the news and at once starts to plan for Jamie's future. The Earl, however, means that Jamie shall cut loose from all of his former associates. He persuades Marget to believe that she is an obstacle to Jamie's future and she reluctantly decides to make the sacrifice and give up her sweetheart. As chief of the clan, Marget commands him to leave. Jamie with heart torn asunder departs for his mother's yacht. Marget decides to sail out to somewhere in the west where her father and his father were wont to sail with the fishing boats. Before she cuts the ropes that hold the frail old hulk in which she lives to the island shore she sets ashore her pets and writes a note, places it on the strap collar of her favored little goat, and sends it abroad. Grouchy, gloomy Pitcairn, the village atheist who feared no one and hated himself, has always refused to obey the rulings of Marget. Pitcairn is in a troubled sleep the night Marget cuts loose in her unseaworthy craft, and in a wakeful moment he hears the bleating of the goat at his door. He is about to drive the animal away when he finds the note Marget has written. Looking seaward he sees the old craft tossing in the sea and he realizes what has happened. The village is aroused and the church bell set to ringing. Down to the surf line rush the people. Pitcairn sends a messenger to the yacht to get Jamie. Lowering a boat he rushes to the hulk and just as the waters are closing in on the cabin he rescues his sweetheart and the atheist falls to his knees and utters a prayer for the first time in his life. Jamie takes Marget back to the yacht, a reconciliation between the girl and the Earl follows and the dreams of the courtship begin all over again but they are real dreams because they have come true.
