An experienced climber has been reported missing in the Cuillin mountains on the Isle of Skye. The missing man, Frank, is a 'Munro bagger', a hill walker attempting to climb every mountain in Scotland that is over 3,000 feet. Frank had only a handful of Munros left to tick off his list. Despite not knowing his exact location, search teams work relentlessly to find him as the weather worsens. Meanwhile, 200 miles north on Orkney, a warrant has been issued to search a property where the residents are suspected of dealing Class A drugs. In Glencoe, officers Stephen Cooper and Roddy Sandeman respond to a distress call on the Ballachulish bridge, where a nesting cormorant has become trapped. And in Inverness, weekend party-goers hit the city streets, and two cops have to deal with aggressive behaviour at closing time.
