Hermit the Strombonin found himself teleported into another dimension. He could get back if he wanted to, but there's one problem: he can't leave without his Strombone. 15 years later, Gwen the Dandidoo and her adoptive sister find themselves in the same dimension. They could help Hermit... but Gwen is being haunted by the ghosts of her dark past. Are they just an illusion... or is something bigger at stake?
