You follow the alleys looking for shelter

You sneak down the alleys trying every door you come across. All locked. Then theres something stirring low to the ground ahead. You stop. You see a quick rustle of movement and a gun shot rings out. The bullet catches your right arm, shattering bone. You whirl and fall to the ground screaming in pain. "I'm sorry", I thought you was one of them!", A man's voice sounds from the shadows.
