Planning idea for film

Ex school student Joshua Owen left school at the age of 16 due to being bullied on a daily basis. Josh was bullied by the popular students at his school. As a result of this he has had a very lonely childhood. Now he's 18 and can drive, therefore he uses this to his advantage. He is on the search for the bullies to seek revenge. Once he finds the bullies he captures them and buries them alive to watch them suffer for everything they have put him though.
