Thiriotrofeio arrenon enantion thileon (1985)

By an innocent booking misunderstanding, four mischievous senior high school students looking for a good time and chaperoned by Takis, a laid-back math teacher, will eventually find themselves at a prestigious and luxurious hotel, far beyond their wildest imagination. In addition, without knowing it, at the very same hotel spend their cloudless summer vacation days a group of innocent, well-bred, high-school seniors; all sheltered and virginal bashful girls under their stern English teacher's ever-watchful eye, the vigilant Chariclia. But before long, what started as a joke and a welcoming twist of fate, will shortly turn into a "cultural" exchange of the craziest sort, where the girls' social status and the long-suppressed teenage impulses will finally meet the naughty and reckless world of the raunchy teenage average Joes. Without a doubt, this is going to be the best summer ever.
