Two German girls, one a redhead (Sabina Karen) and one a blonde (Ulrike Lary), are on holiday in Paris and get chatted up by Richard and Guy. On their double date the blonde is keen for sex with Richard, but the redhead is much more reluctant. Therefore, after he finally fails to go all the way with the redhead, Guy joins the other two. The blonde takes him on and Richard goes off to join the redhead, and succeeds. The redhead then gets most of the action, until the girls leave Paris.
