Lacy Steele has been dispatched to the Hamptons with the tall order to make amends with her estranged sister, Riley, and her ex-fiancé, Robert. The time has come to decide which of her friends to take as her date: Tosh or Jason. As if to add to her already high stress level, she'll be spending the weekend with Robert's certifiable family, and his aunt has declared a ban on dessert.
Sugarless and forced to deal with Riley's never-ceasing drama, Robert's inappropriate advances, and his crazy family's odd behavior, Lacy thinks things can't get any worse until she becomes the suspect in a murder. Now she must unravel the clues to clear her name, but the only way to do that is to become a target herself.
