Overview: With the bridge repaired, Archie plans an elaborate opening ceremony. He is horrified to learn that the council have approved Stuart McIntosh's proposal to turn Ben Bogle into a holiday village. Molly enlists Duncan's help to prove that the proposed site is actually a place of historical interest but they must work against the clock if they are going to save the mountain. All Stuart's plans are scuppered when Duncan finds a secret passage full of artefacts and Lexie discovers that Stuart made a pass at Stella.
