A new season for tv show "Sing That Tune" starts for boy band Heartbeat. Nolan Knight is not at all prepared for it. His wife is leaving him while he gets ready for this season. No one but himself and his brother Jon knows about it.
Meanwhile in Boston, single sister/mother Claire Mansfield holds dreams in her heart. She's always singing, song writing. Never finds the time while raising her twin sisters Darla and Nina. Claire's parents had been a car crash. They had died. She has been raising her sisters on her own since she was eighteen.
Now she is twenty years old.
Darla video tapes her sister singing with other sister Nina. Sends it in for the tv show contest. Much to Claire's surprise she gets an official call from band member Jonathan Knight welcoming her on the newest season.
Fate is calling Claire.
Will she answer?
