De Flat (1996)

As the Dutch thriller De Flat (1996) begins, a successful doctor with a young son moves into a chic seaside apartment in an attempt to put some distance between herself and her recently estranged husband. Roos’s (Renée Soutendijk) desire to unwind and take stock of her life is rudely interrupted, however, when her housekeeper’s corpse is found in her apartment. When a series of obscene phone calls follows, Roos realizes that she’s the target of a madman. A number of ostensibly helpful studs quickly rush to the doctor’s aid, but she’s unnerved not to know which is being gallant and which might be a psychopath. You’ve got to give Roos credit, though--no knife-wielding killer is going to separate her from her routine. She glides nudely through her apartment as though everything’s right in the world (and when Soutendijk’s naked, it is).
