Police Constable Hamish MacBeth must solve some mysteries during the Christmas season and bring Yuletide cheer to a town that has long been devoid of it. The Calvinist element in Lochdubh forbids holiday celebrations. Hamish must protect an unhappy girl, decipher the secrets of a frightened elderly woman, and retrieve stolen holiday goods in short time before the church bells toll. Otherwise, Lochdubh will face another dreary winter without the warm embrace of A Highland Christmas.
