This episode finds the police dealing with cases old and new, helping members of the public and celebrities alike. Chief Commissioner Cameron Miekelson likes to think of himself as an innovator and a forward thinker, and is happy to share his new strategies and initiatives. While his fresh projects involving canine recruitment and working hours are still a work in progress, it's his Police Complaint Listening Scheme that really makes a big noise. And who better to deal with the complainants one-to-one than the chief himself? Investigating a rather nasty case, detectives Squire and McGill seek the expertise of their colleague DI Longstaff, the cold case expert. If there is a link between the current case and some bygone brutality, then he will join the dots - assuming his delicate stomach can deal with the bloody details. Meanwhile, in the countryside, PC Charlie MacIntosh has a decision to make - offered an exciting opportunity away from the police, will he run for the hills or will he stay long enough to discover who his new policing partner will be? In the station, officers Karen and Sharon deal with a rowdy Burns Night that got out of control, filling their custody suite with kilted brawlers and poetic crooners!
