Inside Amy (Swingers Massacre)

Charlie, a well to do suburbanite/lawyer, is so bored with his perfect life and beautiful wife Amy. So he suggests to his loving wife that they go to a swingers party. After a little convincing she agrees, but things don't go as well as poor Charlie had hoped once they get to the party. Amy's having a great time, all the guys are into her. Charlie on the other hand is having a bit of trouble rising to the occasion. Soon after the party, Charlie launches into a jealous murder spree and begins slaughtering anyone who has or wants to sleep with his wife.
