故事发生在爱荷华州,传说一位天使(约翰·特拉沃尔塔 John Travolta 饰)降临在了此处。昆兰(威廉·赫特 William Hurt 饰)是一名报社记者,得知这一消息,他立刻自告奋勇毛遂自荐,想要到那里进行调查和采访,期望获得珍贵的第一手消息。然而,昆兰的老板却并不信任这个常常惹出麻烦的员工,他派出了多萝西(安迪·麦克道威尔 Andie MacDowell 饰)和昆兰同行。 一行人抵达了目的地,可出现在他们眼前的却并非他们想象中圣洁严肃的天使,而是一个玩世不恭放浪形骸烟酒具沾的花花公子。就在众人以为这一切都只是一个骗局之时,这位花花公子却展现出了令人震惊的神力。Frank Quinlan and Huey Driscoll, two reporters from a Chicago-based tabloid, along with Dorothy Winters, an 'angel expert', are asked to travel to rural Iowa to investigate a claim from an old woman that she shares her house with a real, live archangel named Michael. Upon arrival, they see that her claims are true - but Michael is not what they expected: he smokes, drinks beer, has a very active libido and has a rather colourful vocabulary. In fact, they would never believe it were it not for the two feathery wings protruding from his back. Michael agrees to travel to Chicago with the threesome, but what they don't realise is that the journey they are about to undertake will change their lives forever.
