The Scottish Police Force aims to spread goodwill this Christmas by locking up Bad Santas. Volunteer Officer Ken Beattie tends to an old acquaintance up an alley, while McLaren and Fletcher tame wild party animals. Singh and McKirdy bag the first arrest of the new year, and Officer Karen keeps cool when Bobby gets burnt by dodgy aftershave. A special festive edition of the police comedy, starring Jack Docherty, Grado, Manjot Sumal, Sally Reid and Jordan Young, with guests Gayle Telfer Stevens and Mark Dallas
