Ideas and Concepts

Idea 1 - The suspect is travelling through the London underground network looking suspicious. i.e. hooded jumper, backpack, shaded/obscured face. A voice over in the form of a security guard is conversing with other security in the system, they all treat the suspect with suspicion and follow him via the CCTV network. The suspect finally comes to a halt on the platform, but it is the woman next to him that drops a bag and runs. The film ends just before the bomb explodes at the man's feet.

Idea 2- A man is travelling on the underground, a woman sitting next to him drops her purse. He looks shifty and looks around before taking the wallet. It insinuates that he has stolen the wallet, but instead he goes to a police station and hands it in. This narrative is simpler, and may be more effective in a short film.
