A chilling thriller as compulsive as Emma Cline's The Girls.

It's the Summer of 1967. The sun shines brightly over Boundary lake, a holiday haven on the US-Canadian border. Families relax in the heat, happy and carefree. Hours tick away to the sound of radios playing 'Lucy in the Sky with Diamonds' and 'A Whiter Shade of Pale'. Children run along the beach as the heady smell of barbecues fills the air. Zaza Mulligan and Sissy Morgan, with their long, tanned legs and silky hair, relish their growing reputation as the red and blond Lolitas. Life seems idyllic.

But then Zaza disappears, and the skies begin to cloud over...
