故事是这样的：一个年轻的外交官刚调到伦敦，急着找住处，相中了一栋老宅的地下室。杰克·莱蒙全程带着“我好像上当了”的困惑表情，跟弗雷德·阿斯泰尔那段用家具当道具的即兴踢踏舞，比台词更抢戏。看完你会明白：有时候最危险的房东，反而是生活中最有趣的相遇。女房东年轻貌美，举止优雅，可邻居们都在背后议论——说她涉嫌用砒霜毒死了自己的丈夫。适合想看“不闹腾的喜剧”的观众：不需要刻意挠你痒痒，等你琢磨过来，笑点已经从字幕里溢出来了。 ☀。

When William Gridley arrives from the US in London, he rents part of Carly Hardwicke's house from her and promptly begins to fall in love. Gridley doesn't know that many people think she killed her husband but his boss, the American ambassador, knows and doesn't take this lapse of judgement lightly. Since Carly is also American, Gridley saves his job by introducing her to the ambassador, who is promptly smitten and promises to help her. So when a Scotland Yard detective arrives, wanting to get to the truth one way or another, they say they'll help him. And then the comedic complications really begin.
