A light on in Chicago

Mary Plover, a 24-year-old violin and string orchestra teacher, is known for her fantastic violin skills. No matter what everyone says, she still believes she isn't perfect, even when the famous Chicago band, Fall Out Boy, ask her to be a solo violinist for their new album; Folie à deux.
As her and her team of string musicians record with the band and all become close, Mary Plover starts to notice her growing feelings for a certain Patrick Stump.
Kate Rune, one of Mary's violin students, is in the recording process with Mary's orchestra, hiding a deep and dark secret about her home life. As she goes further and further, her light slowly begins to fade, that is until she meets someone who she can talk about her issues with; Pete Wentz.
