Midsummer’s Eve. Bonfires dot the English countryside and flicker in the ancient Forest of Dean as costumed revelers dance and drink the night away. But when the sun rises, a local girl, Maddie Friar, has vanished, last seen heading to a party in a forest commune called “The Clearing.” Her sister Adele reports her missing but the local police say Maddie was a known party girl and probably ran off with some boy, or maybe the “Cinderman” got her, referring to a local legend of a forest spirit said to haunt the woods in search of a lost daughter. Eminent criminologist and academic Dr. Laughton Rees also knows about the Cinderman. She has found dozens of historical missing persons cases in these woods, all women, all attributed to this legend. But she doesn’t believe in legends; she believes in facts, so she heads to the forest and, with help from Adele, starts questioning everyone, from the mysterious Earl, lord of the crumbling abbey in the heart of the forest, to the charismatic leader of The Clearing. But as Laughton slowly begins to unravel the legend of the Cinderman and realizes it is bound by blood to Adele and Maddies’ dark past, she also discovers too late that the truth is far uglier, and far more dangerous, than any mythical monster.
