Mia is still grieving the death of her mother when she and her friends discover a party trick involving a mysterious embalmed hand. By holding the hand and saying “talk to me,” they can briefly invite spirits into their bodies. What starts as a dangerous social-media thrill becomes addictive, especially for Mia, who thinks the hand may let her reconnect with someone she lost. But when one session goes too far, the line between the living and the dead breaks open, and Mia’s grief becomes the perfect doorway for something far more sinister.
