Dietrich is a sexy jewel thief who robs (and lives) by manipulating every male in her vicinity. Cooper, as an auto engineer on a vacation in Spain, proves no different, as he unwittingly carries the stolen gems for her across the Spanish border, but she soon falls for his energetic sincerity (not to mention his tall, broad shoulders) but must continue to lie to him to avoid arrest and disgrace. Eventually, instead of turning thieves together (which would have been more interesting), they decide to go straight and return the jewels. This is the type of thing that started to pop up in these kind of films after the reforms of the early thirties. The film's second half is thus less fun than its first, but it emerges as a solid comedy/romance package.
