I know this description is going to be very vague and not make a lot of sense but if anyone could make sense of it I'd be extremely grateful!

Could anyone name this film from this setting- a women has been kept hostage in the bedroom of her own house, the walls have been covered in the egg packaging foamed cardboard that cuts out any sound. She advertised for a flatmate and a man answered who became obsessed by her, when she did not return the love he locked her up to make a point.

Another scene is her writing a HELP ME! Note and posting it through the vents in her room but falling in the garden where the guy finds it.

Towards the end she's in the bath where she tries to seduce him then he makes them a romantic meal where she tries to escape...

Here are some things I know which may help:

-it was released between 10-20 years ago around the early 90s.
-the actors by what i can remember wasn't that famous
-american
-was on TV maybe cable im not sure
-and all i think i can remember from the title are words simular to: dead, bolt, locked.. as you can see i really dont know!

PLEASE COULD ANYONE WHO MAY KNOW THIS FILM TELL ME ANYTHING ABOUT IT COS I THINK IM LOSING MY MIND TRYING TO FIGURE THIS FILM OUT!

UK, USA, Canada.. ect, cable or basic chennal? Just trying to get a little more detail... because the movie sounds fimilar, but that's a basic plot for a lot of movies.. lol well good luck, I'm sure someone can help you soon.. :)

Ive put down the answers to the questions you raised to the best I can and hope someone does help through our information. And I hope I can help you 1 day tooo!

Deadbolt 1992 TV starring Justine Bateman from FAMILY TIES:
When medical student Marty places an ad for a roommate, her ad is answered by handsome, clean-cut Alec. At first Alec seems to be a wonderful roommate; supportive, considerate and a real friend. However, Alec's affection turns to obsession as he plots to manipulate and control all aspects of Marty's life, imprison her in her own apartment and make her his.

You're welcome... you pretty much helped with the dead, bolt, locked clue... I remember who starred in it and made sure of the name!
