Was there any pre-Code actress more cooly glamorous than Kay Francis? The story that has her a married woman trying to resist the charms of a private detective (the less than amazing George Brent) who's trying to entrap her is pretty average fare, but it's livened up a bit by a con artist (Glenda Farrell) taking advantage of his assistant (Allen Jenkins), getting drunk on champagne cocktails among other things. In fact, this is one where I might have been more interested in the subplot of the supporting players.
The main story is set in motion because Francis's character is being blackmailed and she feels she can't tell her husband the truth, so he suspects her of having an affair. Without going into all the details, it's a pretty contrived scenario that leads her to Cuba. Aside from Francis's wardrobe and a glimpse of an airplane (the seating section for which was amusing to me) there aren't really a lot of interesting period details, and don't come here expecting any pre-Code naughtiness. Rather predictably, the detective and the woman begin developing feelings for one another in the moonlight, which I'm not sure I was really rooting for. The ultimate fate of the sinister blackmailer (the well-cast Monroe Owsley) was a nice touch though.
