Three misfits build a friendship on the common links of a key, a ghost and a mystery. Eleven year old Ben Rowan has found a good hiding spot deep in the basement of a house that has long been considered haunted. In the darkness, Ben finds a mysterious object and from the first moment he touches it, it gives him surprising advantage over his enemies. The key Ben has discovered connects him to the ghost who inhabits the old manor house. The ghost doesn't take kindly to intruders; however it does feel indebted to Ben for unearthing the precious key.
