At the turn of the 20th century, "Brand" (Louis Jourdan) is sitting in Vienna contemplating not only a duel the next morning - which he has no intention of attending - but also a letter he has recently received from "Lisa" (Joan Fontaine) explaining her infatuation with him when she was his young neighbour and he an aspiring pianist.
