What can a young couple do, if they realize they are just in a movie? They should do something to prevent the film from ending. Well, this is the last scene of the film. The road that leads us to this point is a chain of strange events that are weirdly connected.There is revenge, blood, and an investigation after someone, who may not be the part of the story. But it is just a film, nothing should be taken seriously.
