As a senior in high school, Leah and her best friend Christian lead their volleyball team to victory after victory. But when Leah, Christian and their team break into their town's haunted mansion to celebrate a win, everything changes. The girls discover that within the house's walls, wounds magically heal, haircuts grow back, even death can be undone.
But as the girls' visits to the house turn increasingly dangerous, Leah remains untouched by the house's magic. Desperate to hide her differences, Leah begs her identical twin, Laura, to impersonate her for one night. But the house won't be deceived . . .
Twenty years later, Leah has built a life elsewhere - pregnant, and convinced she's carrying twins, despite scans only showing a single baby girl. When a call from the blue pulls Leah back to her hometown, the secrets left in the house are about to collide with the present.
