一个由催眠师沃格勒率领的剧团在前往斯德哥尔摩途中的一个小镇上,被当地的警察局长和相关人等扣留盘查,他们被勒令要当众表演魔术,以验证是否存在超自然现象。结果他们的耍宝把戏露馅,但在逗留过程中他们却经历了许多意想不到的奇遇和变化,最终剧团受到国王的召见而重新上路。When 'Vogler's Magnetic Health Theater' comes to town, there's bound to be a spectacle. Reading reports of a variety of supernatural disturbances at Vogler's prior performances abroad, the leading townspeople (including the police chief and medical examiner) request that their troupe provide them a sample of their act, before allowing them public audiences. The scientific-minded disbelievers try to expose them as charlatans, but Vogler and his crew prove too clever for them.
