Tom (Gary Cooper) encounters Madeleine (Marlene Dietrich) on his way to holiday in Spain. Unknown to him is the fact that she has just stolen $2 worth of pearls and is trying to smuggle them into Spain. She slips the pearls into his jacket pocket without him noticing so she can avoid the customs search. However, he takes off his jacket and packs it into his suitcase forcing her to stick with him until a moment arises where she can get the pearls back. Things dont work out as planned for her as when they part company, Tom still has possession of the pearls. Her partner in crime Carlos (John Halliday) is not happy with her when Tom suddenly shows up again. However, Madeleine is romatically won over by Tom, who is still unaware that he is carrying the valuable pearls, and this changes her plans.....
The film has a good cast with a special mention for Zeffie Tilbury as "Aunt Olga" who turns up late in the film - an old, frail lady on the outside but a cold, emotionless criminal at heart. She advises Madeleine to forget about love - it is much better to have the memory. There are many good scenes, eg, the end scene at dinner when Tom gradually reveals to Carlos what he knows about the theft, the beginning scene when Madeleine is carrying out her scam, the scene at customs on the border of Spain where we are unsure of who is going to get busted and how, etc. The story gets going from the outset and is played with humour. Cooper is funny as the salesman, eg, when he discusses which is the better word - "delighted" or "glad" - to his boss before he goes on holiday. The good cast keep the story going but unfortunately, the ending lets things down a bit. It's far too goody-goody.
