When the guys happen upon Richard the gardener, they learn about Roger Tempest’s other castle, Aldourie Castle in Scotland. It also happens to be on the lake where the Loch Ness Monster supposedly resides. After Richard shares with them his own personal account of his “Nessie” sighting, the guys decide to make this a “guys only” weekend to go hunt down the elusive creature. The girls, meanwhile, are freaked out by noises they hear in the castle and decide to bring in a professional ghost hunter — although they may not be ready to find out the truth.
