The actress plays a popstar/singer role and argues with her songwriter/bf and doesn’t give him credit early in the movie. And in another scene she puts on a dress and everyone pressures her to perform a song after they drink dance. The older woman in the film is the lady of the household and has a younger lover and she tells him to make a move on her. At the end of the movie, I think he or another character walks through the party that they’re having outside at night and shoots himself.
