must be sucky to be able to see ghosts, there'd be enough stress enough as a parent, imagine if someone saw you acting strange or 'talking to ghosts' and end up labeled as unstable and separated you from your kid (versus 'good' spirits being able to help you)
That said interesting it seems to be inherited too
There's not much more that needs to be said. Mom and Son cross paths with a killer ghost, and now the son is haunted. Ghost kid, who was probably bound to that barred park, is now free.
