Chasing notorious, mythical legends and ghosts was exciting to them, not "cool" to the other kids around. So they lived their lives on the outside of the "in" crowd.

Trying to impress Brandy, Charlie accepts a dare from her brother Nick that says he and his friends must spend Halloween night in a house long rumored to be haunted.What seems to be an easy challenge quickly turns out to be a night of frights as Charlie, Nick and Alex find themselves in the fight of their lives trying to out smart (and outrun) their new nemesis, a ghost dog named Salty, who does whatever he can to make this the worst night of their lives...。
