The Buccaneer's Girl of the title, played by Yvonne de Carlo, is Deborah McCoy, an entertainer who's been around a bit. While visiting New Orleans, Deborah falls in love with aristocratic Frederick Baptiste (Philip Friend), who turns out to be a pirate. Baptiste is basically a decent fellow: his piracy is aimed exclusively at the crooked shipowner who destroyed his father. Deborah is a bit more mercenary, hoping to marry into wealth by posing as a high-born lady. By the seventh reel, however, she's perfectly content to settle down with the raffish Baptiste. Though played tongue-in-cheek, Buccaneer's Girl never resorts to "camp": it invites the audience to laugh with the film, rather than at it.
