until dawn

A person in a dark hoodie confronts a woman in a purple jacket against a misty, mountainous backdrop, then the scene cuts to a woman with a bloodied face screaming, followed by a close-up of a bloodied face lying on the ground, then a man being attacked by a grotesque creature in a forest, and finally a close-up of a man's bloodied face, all leading to a title card for "Until Dawn" featuring a blue butterfly.
