The things i remember about the movie is:
Man and women (Maybe wife and husband), they are in love.
Man and woman tries to drown each other in a jacuzzi.
Man / husband catches her having sex with another man trough a place made of glass in some kind of an orgie / swinger.
The Winding of the movie:
The woman has put the man in a wheelchair and man ends up in some kind of a institution.
Movie ending, abusive woman puts man in wheelchair
Re: Movie ending, abusive woman puts man in wheelchair
Can you clarify what you meant about them attempting to drown one another? Was it a fight or a suicide pact?
