I’m trying to find a film I once watched but the usual search methods are failing me, so I think at least one of the following details must be wrong:
There’s a small town or village suffering from some ghostly nonsense. I think it includes a car full of teenagers driving through the town causing mayhem. Turns out they’re actually dead. The protagonist (who I think is an outsider - they usually are) figures out that the teenagers were at a party where something terrible happened - murder and maybe rape. Once all that is in the open the ghosts are happy. I think the protagonist is a woman (I originally thought it might have been Saoirse Ronan but I was wrong about that, so maybe it isn’t even a woman) and I thought it was an Irish film. Maybe I’ve mixed up two films. Maybe it was a short TV series rather than a film. Made in the last 20 years I’d guess. Any guesses? Vague, I know.
