The Final Broadcast

A man wakes up in the middle of the street. There isn't a single person in sight. He has no idea of what could have happened. He doesn't even remember his name. His only clues are a Most Wanted poster, photographs, and letters to people he's never heard of. None of this means anything to him. The man chances upon Kristen and Samuel - both badly injured. Neither of the two can provide an explanation. But Kristen has a radio that intermittently receives some sort of broadcast - someone else is out there. The three of them gather supplies and head for a nearby radio station - the answer must be there.
