A strikingly beautiful girl of nineteen's powers as a spiritual healer make her the community sweetheart, but she struggles to maintain her sanity as her father forces her into the family business – of mass murder.

Good logline! Had me interested. The term strikingly beautiful and sweetheart seem a little contradictory for me, maybe something more "naive"?

(I meant 'put' not 'puts') Sorry.

First of all that sounds like an awesome story! Good work. Perhaps:

"A beautiful girl of nineteen's powers as a spiritual healer has made her the community sweetheart, but also puts her sanity to the test as her father forces her into the family business of mass murder."

Keep up the story!! Good Luck!

Ooooohh?the dichotomy of healing and destruction. This can be very tasty.
Two suggestions: 1) Leave out ?beautiful?, because anyone they cast will be that. 2) and tone down the ?mass murder? to ?contract? killer. Very few mass murderers? kids follow in their parents footsteps.
Overall, I like it.
