Baz Ashmawy hosts a musical game show featuring some of the country's worst singers, all of whom hope to 'change their tune' and win an amazing cash prize. Five truly terrible singers perform a classic song for a live studio audience; after each ear-splitting performance, a curtain will fall and the singer will undergo weeks of training to try and improve their voice. Their transformation is revealed to the audience in an instant as they sing to win the show. Can any of them change their tune?
