Exile (Monday and for the next two Mondays, 8.30pm, UKTV) is set up north, in Lancashire also here known as a "shithole". So there is English rain, a gloomy, dirty house where an old man with Alzheimer's - who was once a fearless respected journalist - rustles about fruitlessly in his dusty study, calls for his long-gone secretary and has to have his bum wiped by his harried, depressed and skint care-giving daughter.
His son, Tom, is a hack in London on a glossy scandal sheet where he writes malicious crap, snorts cocaine, drinks too much and has an affair with his boss' wife. He's chucked out on his ear. He has nowhere left to go; so he goes home.
He arrives at the gloomy family heap to be greeted by his sister with: "Jesus, you must be in the shit."
Tom left home 18 years ago after his father found him noseying through his files and beat the hell out of him. Tom can't cope with his father, the memories, the bleakness, the responsibility, but mostly the guilt of having left his sister to cope with all of the above.
So of course he buggers off as fast as he can in his very fast car. Come back, says sis, or when Dad dies, she'll bury him and never let Tom know he's dead and never speak to him again. Somewhere lurking deep inside the wreck of what Tom has become, is a spark of decency. He returns, sis takes off in his fast car, for two weeks, leaving father and son to get on with it.
