Unusual High School

It's a normal time during high school. That is, until a close friend of one of the groups seems to run away. Despite this, many think it was faked, and something bad may have happened to them. Until they discover something horrifying, ghosts... Tons of ghosts in the school that need their help to get over their deaths, from disgruntled teachers to bullied teens, can they help them figure out how to help them all?
