On a sun-hazed afternoon in the Florida Keys, a child goes missing from the beach, and Dr. Mirren Fitzpatrick appeals to the world to help find her daughter. But before police are even on the scene, there are ripples of mistrust. Mirren was drinking at a bar-alone-when her youngest child went missing. Detective Rolle is sympathetic and believes Mirren's claim of innocence when she says someone must have taken Alannah, but his boss is unconvinced. As rumours swirl about Mirren's past, a trial-by-media ensues, and she is turned from a sympathetic figure to the villain. As the international press descend on the small island community, everyone is asking the same question: what did Mirren do before eight-year-old Alannah Fitzpatrick vanished without a trace?
