The drama depicts the surreptitious invasion of the land our farmer cherishes, with devastating consequences, as his livelihood, homestead and family life are threatened by local county lines drugs dealers: urban gangs using the British countryside as a field of operations, moving drugs and money between their inner-city hubs and provincial areas.　　Nathan Williams is a man who runs a farm which has been in his family for generations, caught in a numbing rhythm of work and grief following the death of his wife, Sabine, two years previously. A single parent to teenager Johnny, Nathan is uniquely placed and possesses enough pent-up energy to take on the gangs that threaten to engulf his son.　　Consequently, he embarks on a personal journey that will take him ever further out of his comfort zone into a dark alternative world as he fights to protect his family, his homestead and his legacy. He’s missed all the clues that the country idyll around him has been fatally compromised, contaminated by waves of criminality spreading and mutating virus-like from the city.　　Now Nathan must accept that the rustic atmosphere of his childhood is long gone, replaced by something altogether more perilous. And the only way for Nathan to survive in this brave new world is to learn the rules and fight back.
