Lost Brother

Your parents go on vacation, leaving you and your younger brother home alone. He persuades you to let him attend a nearby party. Reluctantly, you agree. When he doesn't come back and it's almost morning, a feeling of dread starts to set in. You have no choice but to take the car keys and go for him, but not everything is as easy as it seems at first glance. What happened at the party? Can we find him?
