i found this plot summary for the movie Swing. It is the most
detailed one i have seen yet.

Plot Summary: "Swing" is the dance- and music-filled story of Anthony
Verdi (Casey), a young man caught between his dream of being a full-
time musician and the conventional life of his security-minded father
(Skerritt) and long-time fiancé (Waingort). But Anthony has the
encouragement of several important people around him. There is Bill
Verdi, his loving great-uncle (Winters), who is determined that
Anthony will not meet with the same fate as his musician brother,
Anthony's grandfather whom he never knew. Anthony's outrageous bass-
playing roommate (Cohn) knows first-hand the joys and satisfactions
of a musician's life. The head of his great-uncle's nursing home
(Carter) recognizes Anthony's talent and leads him to an important
break. First and foremost there is Christine, the beautiful older
woman (Bisset) he meets in an out-of-this-world forties night club he
chances upon, who teaches him to swing dance. From her he also learns
that swing is a metaphor for life and that, only if he follows his
heart and starts being who he truly is, can real happiness be his.
Along this journey of self-discovery, which includes confronting his
father's expectations and coming to the realization that he and his
fiancé no longer share a common future, a young woman named Tina
(Brenneman) keeps reappearing, a sure sign that Anthony is heading in
the right direction. Barry Bostwick, Christine's late husband and
angelic mentor; Jim Hanks, the all-knowing maitre'd of the night
club; and Adam Tomei, the eccentric drummer of Anthony's trio, round
out the cast.
