Police constable Hamish Macbeth is baffled by two apparently unrelated mysteries: a huge quantity of table salt has been stolen from Rory Campbell's general store; and Geordie Robb, a local bully, is missing. Hamish outwits his superiors when he makes a connection between the two mysteries.

Major Maclean stages a robbery to make a false insurance claim. Before Hamish can settle things quietly, Inspector Bruce instigates a major surveillance operation.

On a mountain trek led by Colonel Don Maxwell, Hamish advises caution once the climbers have reached their goal, but Maxwell urges them on into a dangerous situation.

A hellfire sect leader sees the town as the new Gomorrah. Hamish's reputation is undermined and his tolerance stretched to the limit when he is denounced as the devil incarnate.

Personal crisis takes Hamish to a remote island from which he intends never to return. But he is not alone. Meanwhile, his absence from Lochdubh is keenly felt when his over-zealous replacement makes himself a nuisance.

A family feud at the funeral parlour comes to a head. It is suggested that space aliens have snatched a body from the local burial ground.

Tongues are set wagging in Lochdubh when the lonely local laird, Major Maclean, returns home from holiday with a glamorous fiancee - but is it his animal magnetism or his Highland estate that Serena finds so irresistible? Hamish is to be best man at the wedding, but he already has his hands full coping with Anne Patterson, the overzealous WPC trainee who's been posted to Lochdubh. His convincing performance as the model policeman sweeps Anne off her feet. Will Hamish resist her undoubted charms - and will he discover the true identity of the Major's fiancee before the marital knot is tied?

A gang of ruthless villains descends on Lochdubh, hot on the heels of young tearaway Frankie Bryce and his Aunty Jean, Isobel's best friend in Glasgow. Isobel brings them to Lachie Junior's funeral parlour where Lachie is happy to shelter them - especially once he claps eyes on Jean. Hamish, however, has a big problem. He knows Tam Flood and his henchmen are dangerous, but he can do nothing until they do something. Ignoring Hamish's warnings, TV John takes pre-emptive action, the villagers close ranks, and the old local legend of Wee MacPhee raises its ugly head.

TV John's long-lost brother, the one-eyed, one-legged, one-armed Kenneth McIver, is Sprung from a South American gaol by millionaire Torquil Farquar McFarquar. Ex-patriate McFarquar has a passion for all things Scottish and has heard that Kenneth knows the whereabouts of the real Stone of Destiny, coronation stone of the ancient Scottish kings. Scenting a fortune in the offing, Kenneth sets off for Lochdubh, accompanied by mysterious hypnotist Ava Grimm. Meanwhile, TV John has had premonitions of the impending death of someone very close. How can the villagers convince him it's all in tile mind?

Kenneth and Ava have stolen the Stone of Destiny, and TV John is missing. Hamish, Isobel and a posse from Lochdubh embark on a death-defying trek across mountain and moorland in order to rescue their friend and save a treasured symbol of the nation's heritage. As adversity brings Hamish and Isobel closer together, myth begins to merge with reality and the ghosts of Scotland's past appear to help them on their way, but ultimately there's no salvation without sacrifice.
