Hey I used to love this one movie and I forgot the name of it. Its about this couple that is at their beach house that meets another couple there. The second couple tries to get the first couple to invest in the guys business but it sounds sketchy so they don't invest. After the sumer the first couple goes home and finds out the second couple bought a house next door. They realize that this couple is creepy and stalkerish. The guy of the second couple tries to blackmail the first guy by sending a stripper to his office and getting it on tape. Anyone know what movie IM talking about? It would be awesome if someone did?

No I don't think so. Thanks for trying though.

It appears the movie you are looking may be Dangerous Invitations from 1998 instead of the 2002 version. A review of the movie mentions it was on Cinemax late-night.
