Melia is asked to work undercover. It's uncomfortable. For one thing, she has to live in a tent, in the middle of the windswept and desolate Barton Moss, an area of countryside unexpectedly found in the middle of the City of Salford. Gratifyingly for her, her on-off boyfriend Mickey has been ordered into the same operation - but, unfortunately for both of them, he is on the opposite side, with the Police! Their relationship becomes as tense as the stand-off between the demonstrators and the drilling operation that faces them, each one unwilling to give an inch in their battle either for or against the new source of gas and oil in Britain - made available through 'fracking'. It's a controversial move, but the UK government is determined to catch up with their US counterparts, and they are happy to support the new technology. Meanwhile, Melia is distraught, losing all faith in her new bosses at the Unit; struggling to support her failing cousin; and determined to hold on to Mickey, one way or the other.
