Emmerdale S39 E288 Episode 5795 (Wed 22nd Dec 2010)

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.
