Stella Moon, a banker from Lasselles, comes to Glenbogle informing Archie that he must take a back seat position while she begins fixing the numerous problems concerning the estate. Meanwhile, Hector and Killwillie compete for the presidency of the local golf club.
Now that Stella has taken charge over all estate affairs, she has decided that drastic changes must be made in order to increase profit while decreasing outward expenditures. But when she orders Archie to cut Lexie, Golly and Duncan's salaries in half, the three go on strike, leaving Archie to pick up the pieces.
Stuart Macintosh, a local buildings contractor, comes to Archie with a decent offer for the unused crumbling cottages located on the estate. But all plans are ruined when Stella discovers these cottages and plans to turn them into a new profit maker for the estate. At the same time, Hector joins a secret society while Golly gets a surprise visit from a relation.
Stuart proposes 'Bogle Croft', a new resort which will be situated on the mountain Ben Bogle located on the estate. Furied by this proposal, and the intrusion it will create in his home, Archie begins a campaign to fight the plan, with the help of his family.
A journalist named Graham Lawrence comes to stay at Glenbogle so that he may write an article advertising the estate and all it has to offer. But it turns out that Graham is also Stella's soon-to-be ex-husband, leaving the gang worried that he will take his grudge towards Stella out on his article.
In order so that he may be able to impress his French pen pal, Duncan becomes laird, temporarily, while Archie becomes head ranger. Then the health inspector shows up thinking that Duncan is the real laird of Glenbogle.
As the night of the Midsummer Ball approaches, Archie is determined to make sure everything runs smoothly. But it seems that someone is trying to sabotage the ball and Stella is determined to keep Lexie in the kitchen so that she may be with Archie on the big night.
When Archie and Lexie announce their engagement, the family is stunned and Hector believes it to be a catastrophic mistake. In an uphill battle against customs and tradition, Lexie and Archie vow to stick together. Meanwhile, a killing pike devours all inhabitants of the loch.
The recent family death has left everyone is disbelief and dismay. Molly feels that although it is a sad time, Archie and Lexie should continue on with their wedding plans and although Archie agrees that this is the best thing to do, Lexie feels that it just isn't the right time.
