Curious Under the Stars follows the destinies of the Druids Rest pub landlords, Gareth and Diane. Gareth, a Glan Don native returns home from London after quitting his job as a teacher and buys the Druids Rest with Diane in a hope that setting out on a new life together will save their marriage.

Joining Gareth and Diane along the way are their earthy barman, Emlyn, a living, breathing encyclopia (and narrator of the series) whose knowledge of Glan Don stretches back centuries, cook and darts player extraordinaire, Matty Evans and barmaid, Megan whose simple and straightforward, outlook on life frequently bypasses the strange goings on in the village.
