Poltergay is a 2006 French film directed by Éric Lavaine and based on an idea by Héctor Cabello Reyes.

The script was written by Héctor Cabello Reyes and Éric Lavaine.

Emma and Marc, two young lovers, move into a house which has been uninhabited for thirty years.

They do not know is that in 1979, in a cave under the house, there was a gay disco, which burned down when a foam machine short-circuited, and five bodies were never found.

The ghosts, touched by Marc's problems, do everything in their power to help him get his girl back.
