In Nightlight, five teenagers go into the woods of Covington. It is a forest to which they should not go, because one of his companions committed suicide in him not so long ago. In spite of it the boys decide to go.
We already know that teens like bravado, jokes and challenges to see which one is the bravest. So they go into the forest with a few flashlights, in order to make jokes and see which one is not afraid.
The joke is twisted when in the forest appears “something”. That something seems to be a kind of demonic presence, which is dedicated to chasing the young with unhealthy ideas, or put another way, with the idea of killing them.
In this way, the five young people are going to repent their whole life of the nonsense they did in the forest at night to spend jokes.
