In a small and dark suburb, a group of young friends discovers an ancient and unsettling artifact: a porcelain hand that supposedly allows them to communicate with the dead. Intrigued by the possibility of connecting with the beyond, they decide to conduct a test. As they perform a simple ritual, their curiosity quickly transforms into terror when the experience unleashes forces they cannot control.
Mia, a young woman marked by the loss of her mother, becomes the most eager to experiment with the hand, seeking answers and a connection that will give meaning to her pain. However, what begins as a fun game turns into a horrible nightmare when they start receiving messages from malevolent spirits unwilling to let go of their anger and suffering. As the boundaries between the world of the living and the dead blur, the group's friendship faces extreme tests that reveal dark secrets and hidden fears.
The young people must fight against their own demons while trying to get rid of the hand, but each attempt only leads them to greater despair and horror. The line between life and death becomes increasingly blurred, endangering not only their lives but also their sanity. In this terrifying exploration of life, death, and the price of curiosity, the friends will discover that some doors should never be opened.
