Justin, a human rights lawyer from London, visits his family in Scotland, lost to him since childhood, while his US visa is being processed. A few weeks in Edinburgh, he figures, should be short, sweet and above all enjoyable, but his uncle Rab runs a brothel, the turbulent Birds of Paradise sauna, and a regular who enjoys a sound spanking has just scammed Rab's mum out of her savings. Now poised to do a runner, without paying what's owed, Justin must join his hunt, manage the girls, and survive being pressganged by his uncle and associates back into a life he's long since been removed from. Losing his visa may be the least of his worries.
