In the 1980s, Kate Meaney is hard at work as a junior detective. Busy trailing "suspects" and carefully observing everything around her at the newly opened Green Oaks shopping mall, she forms an unlikely friendship with Adrian, the son of a local shopkeeper. But when this curious, independent-spirited young girl disappears, Adrian falls under suspicion and is hounded out of his home by the press. Then, in 2003, Adrian's sister Lisa--stuck in a dead-end relationship--is working as a manager at Your Music, a discount record store. Every day she tears her hair out at the outrageous behavior of her customers and colleagues. But along with a security guard, Kurt, she becomes entranced by the little girl glimpsed on the mall's surveillance cameras. As their after-hours friendship intensifies, Lisa and Kurt investigate how these sightings might be connected to the unsettling history of Green Oaks itself.
