When twelve-year-old Theresa Martinez's mom dies, money problems force her family to move into her dead grandmother's creepy old mansion. Immediately, strange things start to happen. The powdered sugar she's been searching the kitchen for suddenly falls out of a cupboard. Closed curtains are mysteriously open—all fun stuff for Theresa's new ghost-obsessed friend Kerry. When they find out the reality show, Ghosters, is hosting a contest for the best paranormal recording, Theresa remembers Dad's money problems and vows to win the contest. Along with Joey, her little brother who has Asperger's, the girls use Kerry's ghost-chasing equipment to hopefully capture prizewinning evidence. They soon discover that ghosts are just the tip of the stunning mysteries the old house holds.
