A fledgling rock band on the verge of being discovered make a discovery of their own: a magical ancient amulet that gives them the power to see ghosts – whether they want to or not. Slightly deterred from fame by their newfound responsibility of helping an endless parade of desperate, and sometimes angry, apparitions resolve their unfinished business, the band begrudgingly intertwines their desire for rock and roll success with the lifelong gig of ushering the dead to the other side.

Conta a história de três membros de uma banda fictícia chamada The Problem, que encontrou um amuleto mágico que faz com que eles vejam e falem com fantasmas. Cada episódio mostra a banda ajudando um fantasma ou um grupo de fantasmas a irem para o outro lado.
