It Started out as a Dare

A brother and sister are walking home when a group of kids approached them. They were the kids that liked to pick on the brother, but they weren't there to pick on him. They wanted to go into the abandoned asylum, but the brother didn't want to go, so they just went to the old garden area so that the sister can tell them why the asylum shut down, but before she could finish it started to rain. They went into the asylum and the sister finished telling why it shut done when one of the other kids took out a Ouija board out, letting the evil out and locking everyone in. Now it is up to the sister to get everyone out, as she is the only one that knows about the supernatural in the group. They have to fight possession, spirits, and Satan worshipers. But to get out they have to solve a few mysteries and free some souls. The question in the end is do they all get out and do they really free themselves from the evil of the asylum?
