Grace Dent tells the story of a maverick lawyer and his attempt to win asylum for a Pakistani man who says that - because he's gay - he will be persecuted if returned to Pakistan.

Mike McGarvey is the lawyer: He's eccentric, disorganised and very dyslexic; he failed at school and didn't pursue education until his adult years. He runs his own business which is based in a small suite of offices near the main station in Cardiff. One wall in his office has a distinctive collage of pictures from Disney, Star Wars and the Blues Brothers: things that are 'designed to cheer me up' because 'nearly everyone who comes here tells you they're going to be killed'.

We follow Mike for five months as he tries to find ways to prove that his client is indeed gay. This involves mining his phone for evidence of activity on gay dating sites, and seeking witnesses who will be prepared to say in court that they had a relationship with him.
