To escape her abusive family, Joey needs her string quartet to succeed. But there's not a lot of money in classical music, and a whole lot of competition.
When a bride gets so drunk she forgets she hired a classical string quartet, the second violinist stuns everyone by ripping off a guitar riff on her violin. Seeing a goldmine, the quartet tries to capitalize on this by changing their entire repertoire.
But changing their playlist starts twisting the friendships the quartet members have formed with one another, and now it's going to take a lot more than promises and a new repertoire to save the quartet.
