OP here. Thanks everyone for the feedback. I struggled with this, obviously, between being too wordy but not being too short where the plot doesn't come across and I haven't hit that yet. For a little more background, here is a better synopsis:
Auditions for the high school senior musical come to a standstill when they can?t find a male lead with enough chemistry with the drama club?s star actress, which leads to an unconventional casting choice by the drama teacher. After witnessing the chemistry between her lead actress and her school rival as they argue with each other, the drama teacher persuades the other female to play the romantic opposite instead of a guy. Both leads find themselves in the uncomfortable position of life imitating art as they start to develop feelings for each other while facing increasing scrutiny and opposition from their friends, family and the traditional high school norm.
So it's basically there are no decent acting guys to play the romantic opposite with suitable chemistry with the lead actress. Drama teacher sees lead actress arguing with another girl and sees the chemistry that she wants in her two leads. Two girls have a fairly antagonistic relationship since the one girl wrote a bad review about a play the actress was in in the school newspaper, hence the rivals. So the teacher and lead actress convince the other girl to take the part and the two girls fall in love.
Does that help clarify a little?
