Luciferous (2015)

In a high-rise apartment young parents Alex and Mahsa live with their seven-year-old daughter Mina. Everything about the family is completely normal, uncomfortably real: Their home, their jobs, her school, the way they hold and love each other. The line between fact and fiction is blurred because THEY ARE A REAL family. Until completely normal turns into what they fear the most. Alex's injury opens the door to a malevolent force that attacks and dismantles the family one person at a time: A violent aggressor determined to prove that possession is real, unconscionably disturbing and very different from how it's depicted in the movies.
