Ghost Graduation (2012)

Modesto, a highschool teacher, is hired to tutor ghosts in this Spanish comedy.

A teacher named Modesto who can communicate with the dead has been fired from every school he’s ever worked at, until he gets a job at Monforte where a group of five students who died in a fire during detention still haunt the premises. He helps the ghosts of these students graduate, which is not an easy task since they’ve been dead for 20 years.
