A meek sociologist researching on rape victimization falls for one of his subjects, only to find his involvement brings the attention of the police, and her assailant.

the logline gives us a clear idea of what the movie is about. However, it does not flow smoothly. I would switch it to: "A sociologist that is researching rape victimization brings her assailant's (rapist) attention." This is just an idea on making the logline flow as a single sentence. Hopeully this helps.
