This is doing my head in.
The plot of the movie is:
A family comes home from a little girls funeral, they're grieving. The men go in the truck into the woods and encounter some strange lights and noises. The run home and realise that everyone in the house was experin3cing things at the same time.
I cant remember exactly what happens next but towards the end the 'aliens'reveal who had killed the little girl and they were actually trying to help
