When Rosemary agrees to chaperone her shy, motherless and very dear friend, Tetrine, on a trip to the coast, she didn't expect her friend's fiancé to be such a bore.
Luckily, Rosemary is both an actress and an excellent judge of character. It should be a piece of cake to convince her friend to give this one a pass. Only, it isn't, and the longer they stay at the house on the cliffside, the more convinced Rosemary becomes that her friend's fiancé isn't just a heel - he's got his heart set on murder.
Will Rosemary be able to persuade her friend to leave? Or will Rosemary lose a dear friend?
