Clyde and Stephanie Brenek see little cause for alarm when their youngest daughter Em becomes oddly obsessed with an antique wooden box she purchased at a yard sale. But as Em’s behaviour becomes increasingly erratic, the couple fears the presence of a malevolent force in their midst, only to discover that the box was built to contain a dibbuk, a dislocated spirit that inhabits and ultimately devours its human host. Loosely based on a true story ‘The Possession’ is a pretty effective exorcism horror.
