At some point, his parents would like him to take over the estate, but for that to succeed they need to turn it from a money pit into a viable business. The only trouble is, James junior and senior don't see eye to eye: the father is a traditionalist, the son a reformer. Can Ruth Watson help bring this family together and reverse their fortunes?
