Episode 15 of "Relic hunter"
s01e15 Affaire de Coeur

Event: SCOTLAND 1430 Sydney and Nigel head to the Scottish Highlands searching the missing half of the twine-ing rings that belonged to lovers from the 15th century. In legend whoever wears the rings will find everlasting love together, and their employer, who's got one of the two, is anxious to test the myth. Sydney faces more than a decaying castle and secret passageways, when she discovers that her own lost love, rival Relic Hunter Francois du Marier, is also in pursuit of the ring for far less romantic reasons.
