Your life turned into a nightmare when, after your parents died, you were taken care of by your older brother, Alek. You used to adore him, but now… Now it's hard for you to say who you are to him. Family? An obligation? A burden? Or maybe a problem he wants to get rid of? You knew from the beginning that his girlfriend, Natalie, hated you. She never said it outright, but you felt her hostile glances, saw her fake smiles, heard the sarcastic comments thrown in the background. She was just waiting for an opportunity to get rid of you. And she finally got it. It was just a bite. At least that's what you thought. Maybe a dog bite, maybe some weird insect bite. But Natalie saw the mark on your hand and immediately started having hysterics. According to her, it was a sign – a sign that you were no longer yourself. That you had become… something else. Alek believed her. He didn't even try to listen to you. He just said it was for safety. That it's only 24 hours. That if you're still yourself after that, he'll let you go. If not... you'll stay here forever. Or worse. Now you're sitting in a cold, dark basement, with a gag in your mouth and your hands tied. Hour after hour passes, and you feel... something. Something inside. Is it fear? Or maybe... something else?
