Dead Rising/Survivors

Frank West is a fictional photojournalist in the video game Dead Rising, he is also the main protagonist of the game. Frank finds himself in the biggest scoop of his career, after hearing of a small town called Willamette in Colorado, being blocked off from the rest of the world. Frank hires a helicopter, and flies over the town.

At first, it looks like a possible riot, or even civic disobedience. Frank asks the helicopter pilot to drop him on a roof of a mall, and to pick him up in three days. He meets a strange man on the roof of the mall, and when asking the man what has happened here, he tells Frank to go in and see for himself. Once he's in the mall, he realizes though, this isn't just some riot. The town is infested with zombies, with him stuck in the middle of it. As he tries to help survivors, and win the Pulitzer Prize, he slowly starts to unravel the mystery behind the zombie infestation.

Frank ends up meeting Brad, and Jessie while escaping the zombies. As both of them stay secretive for a while, Frank does a little bargaining. As Jessie runs out to save Brad from an attacker, Frank accidently hurts her, and after a little talk, Frank takes her place to save Brad. Jessie hands him her handgun, and Frank takes off.

Once reaching Brad, the attacker is the same guy he met on top of the mall, and is now continusly firing at them with a P90 (A Submachine Gun, you cannot get in the game) After defeating him, the man takes off, and while Frank presses Brad for info, Brad tells him nothing until Frank shows him a picture of an old man, which he took in the Entrance Plaze of the mall. Brad seems to have an interest in the photo. Since he does, Frank makes him a deal, Frank shows him the photo, if Brad tells him some info. Brad agrees, and Frank soon finds out both Jessie and Brad are DHS (Homeland Security) agents.
