Five girlfriends who want to show off their boyfriend's singing skills play a bet to see who's the best singer. All couples are given game money to bet on the vocal stages each boyfriend performs. At each stage, judges vote on a dropout, and girlfriends have to bet on her own boyfriend or another's boyfriend to keep the money and win the prize.
