Mairi Cameron has been haunted by a moment that changed her life forever. A dark secret that she reveals to no one made her abandon the world at fifteen and become a nun. Years afterwards, a letter from her father, Laird Cameron, comes to shake her life once more; now that she is of marrying age, he requests her return. Mairi does not know how to react, but the surprises in her life have only begun. Hugh Monteith, a Scottish sailor, and his men are returning to the Highlands, and being left with no food, they are fortunate to find the nunnery. Mairi is among the nuns who go outside to bring them food, and soon, the two realize that their families are neighbors. Maybe this handsome captain can take her with him so that she can travel home safely.
Hugh is delighted to be of assistance to her because he is fascinated by her peculiar character, and as they get closer and closer, Mairi utters a bold idea; Hugh can be her new husband. He is not only a specimen of a man but also kind and caring. Even though they just met, Mairi would prefer to marry him than risk marrying a complete stranger. Everything would be ideal, as Hugh has fallen in love with the strange girl if only he was not part of the reason that made Mairi abandon her life. His brother died at a young age, and Mairi witnessed the boy’s death! If Hugh learns her secret and what happened that day, the last thing he will want to do is marry her. Mairi’s past will revisit her, and the people involved in what happened years ago will return with a vengeance. And when the masks fall, Mairi will have to face what she has been running away from for years…
