In 1814, Evangeline Munroe inherits the Nightshade Diamond along with its curse. Evangeline, practical woman that she is, ignores her aunt's warning that the diamond brings the owner bad luck. She continues her search in earnest for a biddable husband. After a disagreeable but very eligible rogue's carriage crashes into her, Evangeline makes the dubious acquaintance of Connoll, the Marquis of Rawley. Evangeline rejects him immediately as unsuitable, but Connoll admires her honesty and sharp wit. On a lark, he decides to pursue her. Bad luck follows and the curse causes major mishaps. Unless Evangeline trusts and places her faith in Connoll, their fledging relationship is doomed.

In the present, Samantha Jellicose, former art thief, uses her expertise to provide security for her lover, the current Marquis of Rawley and billionaire extraordinaire, Rick's jewel show. Samantha uncovers a hidden diamond stashed in the wall with a letter warning of the curse that follows the jewel. Rick laughs off Samantha's superstitious fears and proceeds with the show. Bad luck descends upon his business and personal life resulting in frayed tempers and nerves. Samantha's instinct screams that they should return the diamond to its hiding place, if only she can convince Rick before complete disaster befalls them.
