were being swept away. but zach didn't know that yet. i just wanted to find georgia, my best friend. and also i just wanted to make sure she was all right. keith morrison (voiceover): zach kept telling himself she was all right. newda, this small town on the coast where georgia lived, was protected by massive concrete sea walls and barriers. so your first thought wasn't, oh god, she's in trouble. it was more, thank god there's a wall. yes. yeah. it's there, there's just no possible way that it could have gotten over that. how did you find out that you were wrong? well, i decided-- i just left. i left work. keith morrison (voiceover): back in indiana, zach's parents, relieved their son was alive, got another email. zach was going to look for georgia. now a whole new set of concerns like i wasn't exactly sure where she was. so once we figured that out and we looked it up on the map, well, it wasn't far away.
