Dom and Melinda head back to Harrow to visit a family they helped back in 2010 and find out whether the cowboy responsible has received his just deserts. College lecturer Rae Green had decided to extend his three-bedroom terraced house in Harrow when his elderly father Tony, a Parkinson’s sufferer, moved in. With wife Jenny and children Shamarr, Achish and Janai also in the house, the family desperately needed a loft conversion and a kitchen extension to give them the space they desired. A recommended builder quoted £34,400 for the work, so they took the plunge and remortgaged their house in order to fund the project. After two troubled months, the builder did a runner with £28,000 of the Greens' money, claiming that the taxman was shutting him down. The Greens were left in the chaos that their cowboy builder had left behind. For 84-year-old Tony, this meant sharing a cramped bunk bed with his teenage grandson. While Mel fought tooth and nail to give the family a comfortable home, Dom discovered that the builder was one of the most prolific cowboys he had ever encountered. He uncovered a string of other families who had lost their money and had heard the same excuses – but all at different times, proving that the builder's sob-story was a pack of lies. Two years on, Melinda is back to see how life has been for the Green family. Meanwhile, Dom finds out that the cowboy has been up to his old tricks. Will he get the justice he so richly deserves?
