It's the most anticipated event of the decade: Big Lou and Fat Bob's wedding and everyone is invited! After a wonderful day, Big Lou crashes back down to earth and finds that she is a victim of her own success. The lure of those famous bacon rolls is preventing her from leaving hungry customers without their daily dose of deliciousness - even to go for a long-awaited honeymoon. Will Big Lou find the happiness she so richly deserves? Everyone in Scotland Street hopes so, but, as Burns warned, the best laid plans ... The relative peace and tranquillity of 44 Scotland Street is about to be disrupted. Irene is to return for a two-month stay, consigning Bertie to a summer camp. Not satisfied with that, she somehow manages to come between the enigmatic nun, Sister Maria-Fiore dei Fiori di Montagna, and her friend, the hagiographer, Antonia Collie. Can a person really change, even after being struck by lightning? Bruce's metamorphosis and new-found outlook on life is put to the test as he prepares to leave his creature comforts for the monastic simplicity of Pluscarden Abbey. His house sitter, meanwhile, gets a little too comfortable in his new life and discovers that the talented Bruce Anderson's shoes are all too easy to slip into. With great taste comes great responsibility.
