I cant be sure I actually saw this movie or someone described it to me --the plot: a rich man invites people for dinner-and suggests they play a game where they pretend they are on a lifeboat and have to choose which people to vote off the vessel for the survival of the rest. Each person has to justify why they are worthy of staying alive. The loser has to leave the room. At the end the rich man and two young people are left-and the rich man excuses himself.
It ends with the two remaining people on a seashore exiting a lifeboat.
I am guessing its a tv movie if its real.
