Three friends are running away from something that is unknown, they come across an empty classroom, where a stranger is hiding. They knock hoping that someone is inside, luckily for them, someone is. They are allowed in by the unknown stranger, and take refuge inside where they think they are safe. After a few hours, the three friends discuss what they think is happening and they come to the conclusion. Whilst these three friends think they are safe, an unknown man is approaching their location, is this who they were running from? After a short discussion they start to wonder who the stranger is, the one who let them into the classroom. The stranger is sitting away from the three friends, but is there a reason why? They ask the stranger to come and join them. However this is the worst mistake they could make. As the stranger approaches the three friends, the unknown man is getting closer.
