Divorce barrister Logan Kendall arrives back in London from a trip overseas to find the whole city fogbound. Unable to reach his flat, he books into the exclusive Royal Parks Hotel, where a costume ball is taking place. Many of the partygoers are also stranded by the fog and while some are happy to bed down for the night in the hotel lounge, Leslie Barnes sweettalks Logan into letting her stay in his suite. Although the pair are attracted to each other, the night passes innocently with Leslie in the bedroom and Logan in the sittingroom. As he leaves the suite for work the next morning, Logan barrels into a ladys maid in the corridor outside the room. On arriving at Chambers, Logan is asked to act as counsel for Lord Rockburn, who is seeking a divorce from his wife. Logan accepts the brief, but then discovers to his horror that Lady Rockburn was a guest at the Royal Parks Hotel ball the previous night, and a cornerstone of the case is alleged impropriety after a maid observed a man leaving her room that morning. Convinced that Lady Rockburn can only be Leslie, Logan tries to back out from the case, until Lord Rockburn produces his chief witness the maid, who shows no sign of recognising Logan after their brief encounter in the hotel corridor. When Leslie calls to return a dressing gown Logan lent her, he invites her to dine with him that evening, still believing her to be Lady Rockburn and intending to inform her of the situation. At the restaurant he lays his cards on the table and Leslie reassures him that she reciprocates his feelings. The romantic evening comes to an abrupt end when Lord Rockburn shows up at the same restaurant accompanied by another woman, and Logan and Leslie are forced to make an unobtrusive early exit to avoid a potentially scandalous public scene. They go back to Logans flat, where he assures Leslie that he has fallen in love with her and will if necessary sacrifice his legal career for her. Meanwhile, Lord Rockburn is informed that a private detective he has on the case has uncovered the identity of his wifes lover. He decides to visit Logan immediately to tell him the good news, and is baffled by Logans horrified reaction when he opens the door. Logan admits him to the flat where Leslie is sitting, throwing himself on Lord Rockburns mercy by confessing that he loves her and is prepared to face the consequences. To his astonishment, the bewildered Lord Rockburn informs him that he has never seen Leslie before in his life. Leslie then confesses that she has gone along with Logans incorrect assumption as a means of seeing how much he would be prepared to give up for her. She tells him that she is in fact a widow, and that he has passed the test with flying colours.
