A group of friends grieving the sudden loss of a close companion decide to conduct a séance as a way to find closure and say their final goodbyes. Using an ancient relic that they believe will help them bridge the gap between the living and the dead, they unwittingly open a door that perhaps should have been left closed. As they gather and initiate the ritual, led by the most driven member of the group, they experience strange and unnerving occurrences that suggest they've connected with something beyond our world.

However, the seemingly harmless intention to communicate with their friend spirals out of control when the entity they've summoned begins to show malevolent behavior. The friends are thrust into a terrifying ordeal where distinguishing between reality and illusion becomes increasingly difficult. As the night progresses, the consequences of their actions become ever more dangerous, putting their lives and souls at risk as they desperately seek a way to end the haunting that they've precipitated. Their bonds of friendship are tested as they confront the dark forces they've unleashed, with the realization that some doors, once opened, might never be closed.
