The synopsis for our thriller opening sequence tells the tale of a teenage girl who, in the past, was friends with a boy. They used to play a lot in a park, especially on the roundabout but one day whilst they were playing with the boys younger brother, the girl accidently knocked him off the roundabout causing him to take a fatal blow to the head and ended up dying. From that day on, the boy threatened to get the girl back and take revenge on what she did to his brother. Since then, the boy was put in a mental institute as he went somewhat insane from what happened that day in the playground and it's impossible for him to get out of the mental institute. The girl however, sees him coming after her all the time to take revenge for his brother.

The opening starts with the girl screaming and running into a graveyard and being followed by the boy who is in fact a figment of her imagination however, the audience do not know this until the end of the film and they think that the boy is actually there. Once again, he states that he will get her. Shocked, the camera rapidly zooms in quickly to an extreme closeup of her eye where we then see a quick flashback she has of the roundabout spinning round and round with no one on it. Echoed voices and laughing children can be heard in the background that are all mashed up so all the words are not audible. The shot of the roundabout then flashes and we see, for a split second, the boy's brother on it. The camera then flashes again and the boy is gone, leaving the roundabout to just spin again with no one else on it. The camera then zooms out of her eye and we see her panicking and breathing heavily. The boy then turns and leaves the graveyard and the girl quickly turns and starts running out of the graveyard. She runs into her friend who asks her why she's running and looks so panicked. We then see a closeup of her face as she breaths really heavily and then the camera quickly cuts to her waking up from a dream.

The rest of the movie incorporates the boy, in her imagination chasing after her to take revenge on her. He starts to kill off all her loved ones as she slowly begins to lose her sanity as he kills off more and more of her loved ones.

In the end of the film we find out that the boy never actually existed away from the mental institute and he had never escaped at all, all the things that he did were actually done by the girl herself as she slipped into a state of insanity through out the film and begun to kill her loved ones herself but saw it as the boy doing it instead of her. In the very end, she ends up in a mental institute herself as we finally find out that she was the main cause of all the insanity and deaths through out the film.
