故事讲述西摩在得到一株以吸取人血产生的奇异花卉后，不惜以牺牲自己的代价来赢取顾客的青睐和美人的芳心。然而在名利双收之时，摩西发现这朵奇花在长大的同时，自己已不能控制它的成长，并且生命也面临危险。良心与名利之间，摩西终于醒悟，于是正邪之战由此展开。该片因缘于歌舞剧，故不可能成为主流作品，而且较正统歌舞剧所不及。其独特之处在于能说会道小花的电影特技和轻松插曲，总的讲仍不失为一部赏心妙品。

Two fast-talking insurance salesmen — Wilbur Boswell and J. Addington Ganzy — help penniless socialite Mary Marsh to turn a dilapidated hotel, which was willed to her, into a thriving success. They soon run into trouble, however, in the form of two sets of rival gangsters who want to break into the hotel safe; also, Mary's mother, Rebecca Marsh, wants her to marry wealthy lawyer John Blackwell, although Mary has fallen in love with Wilbur. And while she takes an instant dislike to Wilbur, Rebecca falls for Ganzy. Adding to the complications is the fact that Blackwell is actually in league with the gangsters. The finale involves nighttime runarounds and a shoot-out in the hotel. During the pitched battle between the rival gangs and the police, Boswell and Ganzy save the jewels, after which Ganzy marries Rebecca, and then gives away Mary at her marriage to Wilbur.
