Hi all. I watched a film around about 20 years ago on sky movies in the early hours of the morning. The film was in colour and englih. I beleive it was an american film but wouldnt rule out australian. I believe it was a thriller. The plot is a young women turns up at either her god fathers or a friend of the family’s house claiming she has no where to live. The couple are reluctant to take her in as they don’t know or recognize her but do anyway. The girl then starts to deliberately cause problems between the 2 and tries suducung each of them behind there backs. I remember the girl leaving her bedroom door open whilst getting changed knowing the guy would see. She also spied on the couple one night after hearing them in there room. I believe the girl gets murdered in the end. Thr girl had long blonde hair whilst the man and girlfriend had brown hair. Thanks for your help.
