Research and Planning: Third plan

I have changed my idea again and thought of another plan for my teaser trailer, it's still going to be a zombie film although it's going to be more about the character, with less emphasis on the zombies. In this trailer there is a man in a garage, he is at a desk with a lamp on the desk which is resting on a lamp. There is a voice over spoken by him as he explains his situation, he is looking for a drug which will stop him from turning into a zombie and as he mentions an area he could get it he marks it with a pen and a shot of it is shown on screen after seeing three or four of these he decides he needs to head to a danger zone, he stabs the map with his knife and an over the shoulder shot shows him cocking his gun, rock music is playing while he does this. The name of the film comes on the screen and there's an atmospheric sound.
