Maine lobsterman Shawn MacKay is enraptured by a redheaded mystery woman who sings opera on a deserted stretch of beach by the cliffs of Avondale. Every time he gets close enough to say hello, she runs away. His narrative of the beautiful songbird earns lighthearted banter from patrons of the Malarkey, a local tavern and gathering place for those in his trade. Shawn hopes that one day he will finally meet the young woman who has piqued his curiosity.

Colleen O'Malley's lifelong desire has always been to sing opera. When two pre-teen boys tell her about a cave with great acoustics hidden at the base of the cliffs along the beach strand, she enters alone, oblivious to the dangers of rising tides that could trap and kill her.

When Shawn decides to walk home by way of the beach strand one evening, he has no idea that his decision will change his life. Forever.
