Incredibly Unique and Beautiful… 1982 one on netflix

A sociologist of misfortune, Tasos, with the help of a private detective, Annita, offers two underachievers, Jason and Prokopis, the admittedly exceptional opportunity to spend twenty days in a luxury hotel, because he wants to study the reactions of two working-class types in a posh environment. There, together with Jason’s best friend, Sardela, they meet the following characters: an underwear entrepreneur, Markos, who wants to sell two of his companies, and two representatives of another entrepreneur who wants to buy them. Meanwhile, Sardelas falls in love with a singer, Jason’s classmate, who is flirting with an actor in order to help her band. Jason falls in love with Anita, who reciprocates his feelings. She reveals to him the “sociologist” game. Jason takes advantage of this and wins five million drachmas.
