Doctor John Watson is visiting the village of St Andrews, Scotland, on a much-needed holiday. Still saddened by the loss of his good friend and companion, Sherlock Holmes, he seeks to put his life back in order. Believing that golf on the famous "Old Course" might be just the tonic that's required, he travels to the Kingdom of Fife and the Royal Hotel to test his remedy. While there, he meets a former adversary who can use his sage counsel. Willingly, he agrees to help in all ways possible, for as Holmes might have remarked with great gusto, "the game is afoot!"
