Nick和Nora 这对搞笑侦探夫妻档总是连手出击调查案件。这回他们要着手的是一位发明家失踪的案子，要找出为何会失踪，且失踪到哪里去了……？

相当成功地将喜剧和悬疑元素交融在一起。William Powell和Myrna Loy 饰演的夫妻档，是影史上第一对塑造成功的屏幕情侣组合！本片导演就是影坛上有『一次OK』之封号的 W.S. Van Dyke，本片他只花了两礼拜就拍摄完毕！由华人黄宗沾担纲摄影指导。本片独有的喜剧悬疑风，也成往后这类型电影的祖师爷。Albert Hackett和Frances Goodrich 根据 Dashiell Hammett 的小说改编成剧本。后来还拍摄了五部续集。

The ghost of a recently deceased family patriarch tries to help his surviving relatives, in part by preventing a marriage that he knows will go wrong.

Adam Larey becomes a fugitive from justice when he escapes after being blamed for a crime he did not commit. He wanders into the desert wastelands and joins an outlaw gang who prey on gold prospectors. Years later, he meets his wife and her gold-prospecting father as they have come there seeking their fortune, and not knowing the danger of the treacherous desert wastes, the poisoned-water holes and the outlaw bands of marauders who roam the desert in search of the gold found by others. He comes to their aid and, eventually, manges to clear his name of the false charge against him.
