Jacob has been missing for three days and messages of support flood in as the search appeal goes national. Up on the moors, everyone is searching and when a faint whimper is heard from a disused building followed by a crash, Leyla and David panic upon realising Jacob is trapped. Leyla makes to go inside, but David pulls her back claiming it's too dangerous - he'll go. Inside, as the building starts to crumble further, David sees Jacob. (thetvdb.com)
