The Bonham family, while rich, were relatively humble. They kept to themselves and mostly out of each other's way - until the siblings each received a strange invitation from the Matriarch, their Grandmother Ellie Bonham. Called together in a remote area of a vast park, Will, Danielle, Fiona, Eliza, Tim, and Gina, along with their spouses and children, convene to discover what their illustrious Grandmother has in store for them - and why they have been summoned.
Instructed to bring something that reminded them of her, most of the siblings bring only flowers and questions, questions that deepen when they stumble upon a large mound of their Grandmother's items, things that were obviously taken from the expansive mansion in which she lives.
That bundle of Knick knacks opens a mystery that will take them one by one, testing loyalties, trust and funneling them into a diabolical scheme that may ultimately break the family apart.
