Maple Bishop has a thriving dollhouse business and a new career as a crime scene consultant for the local sheriff's office. On the surface, she seems to be doing well, but deep down Maple is still reeling from the death of her husband. When the body of an aspiring firefighter - who was close childhood friends with Kenny, the sheriff's deputy and Maple's confidante - is discovered in the charred remains of a burned cabin, Maple is called in to help determine whether the fire was an accident or a case of murder by arson. Realizing there's more to the crime than meets the eye, she sets out to unearth the discrepancies from the scene by re-creating the cabin in miniature. The investigation leads them to Maple's old Boston neighbourhood, forcing her to confront the past she's desperately trying to forget. As Maple and Kenny sift through clues, they uncover dark secrets that hit close to home, unravelling in unexpected ways - and putting their lives in danger.
