I don't remember the name of the movie but a I remember the plot:
Woman kills husband with some pills. The man was swimming and hits his head on a big rock.
Woman tries to marry a guy (that guy was trying to take the woman's money after the marriage), but her son objects. That GUY has a daughter (in fact she was his lover and crime partner). The daughter falls in love with her future step brother.
This is all I remember.
I also tried IMDB but with no results.
Thanks a lot!!

Umm... drowning mona?? Maybe? I'm probably wrong. That doesn't sound quite right.

Thanks for trying but this isn't the title. The part with the drowning it's right at the beginning.
I've just remembered that the guy with the daughter(crime partner) tried to gas the woman in a small beach house. It's also possible that the daughter's name might be Sophie. :confused:
