New horror movie from Sweden, that I found via awesome Quiet Earth, that posted the trailer and short synopsis with it:
Psalm 21 is a thriller about Henrik, a modern young priest living in Stockholm. He has nightmares about his dead mother. One day, he recieves word from the coronary in a remote village, deep in the dark woods of Nothern Sweden: his father, a priest himself, has drowned. The circumstances of the drowning are unexplained.
Henrik drives through the endless forests of Northern Sweden up to the desolate village of his father to investigate the circumstances of his demise. As he learns more about the drowning - and about his father - the door to the unknown cracks open. Shadows from the past emerge from the void. They return to our world with one specific purpose.
