In this spooky comedy, a couple and their adolescent son move into a quiet New England summer cottage. Soon their arrival, a series of strange and increasingly destructive occurrences begin to happen. Not believing in poltergeists, the puzzled parents immediately suspect their son. The real perpetrators are a trio of angry ghosts who want the cabin all to themselves. When the mortal family refuses to move, the ghostly trio (two women and a man) sink two boats belonging to the couples' wealthy uncle. Once again the poor boy is blamed and this nearly drives him insane for he can see the ghosts. More trouble follows when one of the lady spirits falls in love with the handsome uncle.
