In each episode, two stars compete against each other to find out who will see the message "Congratulations, you sing magnificently" on the karaoke screen, and who just comes to watch videos of animals and mountains.
And they will be helped by eight strangers. All of them sing in one way or another. Some do it professionally, while others do it with a bit of a crooked voice, but with soul. Their love for karaoke unites them, and only the score counter will decide.
