Traveling dentist O'Connell traverses South America on his motorcycle for the 'Eversmile' foundation of New Jersey, in a fight not only against cavities, but also against fear, ignorance, indifference - and established antediluvian dentists. During a stop at a lonesome garage he meets Estella, who is supposed to marry a few days later. However she'd rather come with him - to meet a former boyfriend in another town, she says. Expecting problems, he refuses to take her, but she tricks him into it and then tries hard to convince him of her qualities and let her stay with him.
The plot involves the school director bringing in a female inspector to clean up the school. The students decide to kidnap her and replace her with the sexy stripper "aunt" of one of the girls (who is naturally sleeping with several of the guys). The real director meanwhile falls madly in lust with one of her male captors. Meanwhile a goody-good student and her hypocrite father begin to suspect the ruse . . . So will there be a lot of crazy hijinks? Will everything work out happily in the end? Will the entire female cast (and an unfortunate amount of the male cast) find some excuse to get naked?
