Story involved a group of friends. The guys were all in business together I believe and the girlfriends/wives were all close. The girls made a plan to swap husbands for the night and the main character wasn’t aware. Once he figured out what was going on he tried calling his wife who wouldn’t pick up. He ends up planning to leave the business or something and all the friends are distraught and it causes a huge rift between everyone. Don’t remember much else.
