"When the amulet calls, and the third sun falls, a heartbeat stalls."

At a Fossil Park, ancient relics go on display - a golden cat, a witch's broom, mysterious twig-people. A child wearing an amulet enters, unaware of the mayhem she's about to cause.

Bailee Paxton wants to help raise money for her friend, Asher. When she takes her amulet for appraisal, it glows the moment the professor touches it. Before long, he's found in a trance and the relics from his display are missing. Meanwhile, someone... or something, spies on her from the shadows.
