Alison Eastwood, daughter to Hollywood icon Clint Eastwood, is starring in a creepy new indie thriller currently being shopped at Cannes. Directed by some guy named Matthew Arnold, Shadow People follows a CDC doctor (Eastwood) as her research on SUNDS (Sudden Unexplained Nocturnal Death Syndrome) leads her to a supernatural conclusion.

The official synopsis reads:

Shadow People is a psychological thriller that explores the rare medical phenomenon known as SUNDS (Sudden Unexplained Nocturnal Death Syndrome). Millions of people across the globe have had encounters with what they describe as dark, shadowy creatures that visit them at night.

Sometimes horrifying, sometimes deadly, these nocturnal intruders have been described as early as man’s first recorded writings. But what are they? And what do they want?

Small town radio personality Charlie Crowe (Dallas Roberts) is thrust into the mystery when a strange caller relates a terrifying experience during Crowe’s late night call-in show. At the same time CDC Public Health Agent Sophie Lancombe (Eastwood) is hot on the trail of the cause of the rare medical condition known as SUNDS.

Her investigations entwine her with Charlie’s own discoveries and take them both into a dark world and a decades old cover-up about the phenomenon we now call The Shadow People. Once you open the door to the mystery…you’ll never sleep soundly again.

Personally, I have had those moments when I’m in bed, counting sheep, and suddenly the room seems to go especially dark, as if shadows were caving in on me and I can’t move. I always figured these instances to be mild heart attacks due to my over consumption of booze and burritos. But, maybe, it really is just monsters. Talk about dodging a bullet! Goodbye diet!
