A spate of tractor thefts has Mike and Bellamy running round in circles, but as Merton comes to suspect it's all an elaborate insurance fraud, matters take a turn for the worse. The robbers target Steve Calthrop's farm, and the loss of such a valuable piece of equipment proves to be the straw that breaks the camel's back, prompting a volatile domestic dispute and putting Tricia in mortal danger. Meanwhile, Vernon sets himself up in the landscape gardening trade. As usual, it's David who ends up doing all the work, which Vernon may live to regret when his hapless house mate tries to impress him by purchasing a Greek statue on the cheap.
