An opera singer suffering from throat cancer lands in a gig with drug addict and very strict musician who would always push her to sing aloud.

Guys thanks for your comments it really helps :-)

Agreed with the above comments.

It sounds like you're trying to set it up as if the gig is a great opportunity, but?the way it's worded in the logline makes the gig seem like a potentially bad gig not a good one. Perhaps best to describe the drug addict as a genius composer or world renowned musician, etc? instead.

Make sure you have your loglines proofread before letting anyone see them. Usually, one lands a gig, not in a gig. Is the drug addict and musician the same person? It's not clear. "with *a* drug addict and very strict musician who *always pushes* her to sing aloud"?
