After a series of strange events, a young woman concludes that she is a witch with magical powers. Against her will , her family pushes her to undergo psychiatric treatment.

I think you're right, that sounds better :D thank you

Sounds quite interesting. Maybe a "series of Supernatural events" might suffice, I know what Richiev is saying but because it is a series of events it starts to becoming a cluttered logline.

Thanks all for your comments!
According to the plots categorized by Blake Snyder, my story is genre "Superhero". Not so much, because of the whole being a witch.. Actually my intention is that during the script, you are never sure, whether she is crazy or whether she is actually a witch. It's mostly about being misunderstood and showing that we live in a narrow-minded society.
The main character is in no way passive, she has a very strong character.

What do you think of this one?
