When the body of young local man Will Mowbray is found between two rival farms, a bitter feud is reignited. With the two families – the Merricks and the Gilchrists – having been enemies for over 30 years, the team must deduce which of them is responsible.
Bill and Muriel find themselves on opposite sides and both are determined to prove themselves correct. Muriel believes that Ray Gilchirst is the culprit, whilst Bill is convinced that Audrey Merrick is to blame.
Meanwhile, Bill wrestles with introducing Mary to Kelsey, Kelsey makes a new friend at the local comprehensive, and Lydia resents doing Bill's dirty work as the redundancies commence.
