Harker is volunteered to work with a young offenders group in Canley, and immediately takes a shine to Carmel, the organiser of the group. When Carmel's foster son, 14-year-old Scott, goes off the rails, Harker steps in to try and defuse the situation. When one of Scott's friends is found dead from a heroin overdose, Harker discovers that despite previous claims that he is clean, Scott and his friend have been drug running for one of the major dealers on the Bronte. However, the situation is complicated further when Harker discovers that Scott and Carmel have been sleeping together, leaving him conflicted about job responsibility and his friendship with Carmel. Meanwhile, as Stanton and Boulton try to locate a witness, Beech attempts to prevent this due to his corrupt connections.
