Coursework - initial idea for a teen horror/supernatural tv series

For my media television series I have decided to create a series called Limbo. It will be a teen supernatural horror/thriller. The series is about the space in-between life and death which is Limbo but in this situation when you are in Limbo you are in a game show. The plot is about 5 teenagers who are in a car crash and end up in limbo. There will be more teenagers in the show who will be met throughout.
The game show is set in an arena which is split into different sections. Each section has a different environment and supernatural creature in it. The environments and creature in each section will change every day. For example: one section may be set in a forest environment with vampires. They must all try and survive both the supernatural and the harsh environments. When they first enter the arena they will each be given one weapon that they can use to defend themselves with. It’s survival of the fittest. Only one can survive and gets to return back to earth before the accident and does not get into the fatal situation that put them in limbo in the first place. The rest however will face their fate; death.
