Dead Last(2001)

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.
