Das französische Frühstück(1984)

Three girls from Hamburg become stars in an unusual way. Annabella is a poor girl who meets a porn producer who promises her the lead role in his latest big budget erotic movie. Marianne is a young medical student who pays her bills by working in a local bar. One day she gets noticed. Susanne is a hustler, who's approached by a shady photographer who asks her to pose for him for an erotic photo spread. However, he might actually be a pimp and his business might be just a cover for a prostitution ring.
