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.
