The first trailer for Personal Shopper was just released. Kristen Stewart reunites with her “Clouds of Sils Maria” director for this unnerving drama that earned both applause and boos at Cannes.

Stewart plays a young woman living in Paris whose brother dies from a heart problem. Before his death, they made an oath that whomever died first would send the other a sign from beyond the grave. Her ensuing attempts take a number of sharp turns, first with a seemingly literal encounter with a ghost and then later with something much creepier.

IFC Films will release “Personal Shopper” sometime next year.
