Monarch of the Glen - Season 4 (2002)

Archie's old friend David arrives at Glenbogle bringing with him old memories and a business proposition for Archie. Meanwhile, Golly and Duncan continue to battle over Irene while Molly takes pity on a runt wolf cub.

Golly's failing eyesight causes him to accidentally let one of the wolves out of the pen. With a group of naturalists in the new campsite the group sets out trying to find the wandering wolf. But Golly feels that he is no longer an asset to the estate.

While dealing with the large debt Glenbogle is in, Lexie stumbles upon a series of monthly payments that Hector made to a woman named Grace. In the meantime, an art dealer searches the estate for valuable paintings he can buy from the family.

The deadline for the payment of Hector's death duties is looming and Archie has run out of ways to raise the money. Kilwillie offers to buy land off of Archie but he claims that he is not interested. Then when an unsuspected clan MacDonald turns up expecting to take over the estate, Archie is forced to save his home, even if it means self-sacrifice.

There seems to be a ghost haunting Glenbogle and Lexie begins to fear for Archie's life. Meanwhile, Irene must decide whether to stay with Duncan at Glenbogle and raise her child or leave and return to the baby's father.

Lexie throws herself into preparations for the upcoming Ghillies' Ball. However the task is much more complicated than she thought and it's not long before she runs into numerous problems. One of which is the arrival of a new stranger, Paul Bowman, with a secret tie to the MacDonald family that shocks everyone.

While the family tries to cope with the recent news of Hector's secret child, Golly, Duncan and Paul focus on rebuilding Golly's cottage. Convinced that Paul is bad news for the whole family, including his mother, Archie persists in trying to get rid of Paul. But his efforts are futile and Molly decides to pack her bags and leave Glenbogle behind her.
