剧情描述一个犹太拉比的儿子一心想成为百老汇明星,唱歌跳舞。此举遭到家长的强烈反对。他们只想让他成为犹太教仪式中的领唱。但是深深热爱爵士乐的儿子一心只想唱流行歌曲……多年后,背井离乡,更名改姓的他终于登上了舞台,在旧金山的夜店酒吧里,他实现了自己的理想,成了一名爵士歌手。 第一部有声片,但其中只有很少几段对白,但足以让当年的观众大吃一惊。这部影片使歌舞喜剧演员乔尔森(Al Jolson)大享盛名,并彻底改变整个电影业的轨迹。曾多次重拍,1980年版由尼尔·戴蒙和劳伦斯·奥利弗主演。
The crooks in London know how it works. No one carries guns and no one resists the police. Then a new gang appears that go one better. They dress as police and steal from the crooks. This upset's the natural order of the police/criminal relationship and the police and the crooks join forces to catch the IPOs (Impersonating Police Officers), including an armored car robbery in which the police must help the gangs to set a trap.
