Tell me, who would ever think of telling the TRUTH in an advertisement? For example, "Buy cars from this company: they are bulky and not very pretty, but they are very reliable! If any advertiser comes up with such a slogan - he will surely be considered a complete idiot and sent to a madhouse. And so it happened to the hero of this hilarious comedy - the ace of advertising Emory Leeson. After Emory "went crazy" on the basis of the "truthful approach" in advertising products, he was sent to a clinic for the insane to "come to his senses". Here Lison gets acquainted with other "lunatics" and, in particular, with a charming blonde Kathy, for whom he begins to have strong feelings. The life of an advertising agent suddenly "gets better", and in the most inappropriate place for this. At the same time, Lison's "truth method" of advertising suddenly becomes the most effective. The bosses urgently demand to return to the service of their best employee. But the problem is that Emory has already taken root in the clinic and doesn't want to leave!
