Melvin Podgorski is young, naïve, American - and a coffee fanatic. His obsession propels him from Chicago to Glasgow as a scout for US coffee franchise Burbacks. Putting behind him a messy divorce, he's here to make something of himself. And make Glasgow fall in love with coffee.

But Glasgow has one or two surprises in store for Melvin. Firstly, they don't speak American. Not even English. He's got to get his head around the Scottish patter. Next, there's the radical politics he's sort of - by accident, you understand - become involved in. And lastly, there's Nicole, about to become his new favourite obsession.

Is Glasgow ripe for an American invasion? Will the past catch up with the present? Or will Melvin's mania be his making?
