Ireland, west coast.
In a moment of madness, Megan Barry, determined to escape her dismal fishing village life, sets sail in her boss's thirty-two foot sloop, naively thinking anyone can sail. Away on holidays with Helen Featherstone (another bone of contention) at the time, and fed up with her lavish demands, Connor leaps at the chance to return home when he hears his yacht has been stolen.
Meanwhile, after a horrific week lost at sea, Megan is finally washed ashore on a small island in the Celtic Sea where she stumbles upon an illicit poteen-making still, a discovery she believes could get her into far more trouble than she's already in.
Back in Scullymór, a terrible suspicion begins to form in Connor's mind - a suspicion consolidated by a series of strange events. While not wanting to report the theft, he secretly fears for his harebrained housekeeper's safety. Borrowing an ancient fishing boat with an dodgy engine he decides to take the matter into his own hands . . .
