Amy has moved down south to London and is now living an idyllic life with her partner, Dani. But their quiet life quickly gets turned on its head with the arrival of Amy’s brother. Soon they find themselves in a web of deceit as Amy attempts to withhold an important truth from Mark: Dani isn’t Northern. But clearly there’s no better way to fake your Northern heritage than to chug down an entire mug of gravy while putting on a Geordie accent. Howay the lads. But it soon becomes obvious that maintaining this facade is the least of their problems. Something isn’t quite right with Mark – or ?Brown Trow’ as he calls himself. His impromptu visit quickly becomes a lengthy stay. He’s not left the house in days and no one’s come to visit him, either. With tensions flying, can Amy and Dani get to the bottom of Mark’s surprise visit before it’s too late?
