I'm trying to remember a movie that I saw on TV years ago. It tells the story of a rich man (a lawyer I think), who is married to a much younger woman. The movie starts with the woman's birthday, her husband offers her a yacht as a present for her birthday. Later on, it appears that the woman has a lover and she plans along with her lover to kill her husband.

Chosen answer: I'm not 100% sure but I think the film you're talking about is Buried Alive 2.
