The new CID team arrives at Sun Hill, led by the new station commander, Supt Tom Chandler. His pally attitude with the relief doesn't go down well, with the likes of Cryer, Smith and Meadows skeptical. Meadows feels the pressure of facing a disciplinary board hearing following the Beech scandal. New DI Alex Cullen is assigned to head the investigation of an apparently racially motivated harassment of a local family, along with cocky DC Paul Riley and hard-faced DS Debbie McAllister, after complainant Frank Griffiths says Meadows had history with Helen Freeley, whose sons are suspected of racially abusing Griffiths and his family. As facts become apparent, events take a dramatic turn. Meanwhile, new arrival DS Vik Singh dishes the dirt immediately by warning his new colleagues that McAllister is overcompensating for a recent promotion to DS, whilst telling them that Cullen in Chandler's pocket.
