Hitchcock liked to isolate people on trains and ships and force them to interact with whomever was in that setting. In this one, the spoiled brat daughter of tycoon lives the life of a princess on her father's money. She is wasteful and shallow and draws attention in that Paris Hilton kind of way. We know that she must have a good heart but now, anything that happens to her is deserved. Enter her father, who wants to teach her a lesson. After all, she has embarrassed him time and time again. She is going to elope with her nice young man, who finds her a bit insufferable at times. He hangs in there while she tests the limits of her entitlement. She is eventually reduced to fending for herself. Hitchcock does a decent job with this but I think there could have been a bit more to it. He got just a bit lazy here. Still, it is billed as a comedy, not "The Scarlet Letter," so there is a lighter touch. It's certainly worth a peek.
