I remember my brother bought me a bootleg cd that contain various short film. one of them is a zombie movie where there's a group of friends living in a small town after the breakout where they isolated them zombies. they were living normally until conflict arrive, then one of them (if my memory is correct) tried to give the zombies food but got grab and accidentally release them all. at the end there's a short montage showcasing the zombies roaming around. and there's this particular scene in the mall or clothing shop which the zombies looking up at the tv. the movie itself isn't that long and it seems to be made by indie studio
adding some detail here, if i remember correctly, when the second outbreak happens, there a scene where the group was in some kind of living room and a large windows behind their back, and there this shot that similar to this image mrwallpaper.com/images/hd/zombie-hands-in-window-a3ef0baupsjxccad.jpg
