A single procuress use voodoo's power for manipulating more than a hundred prostitutes, till day when all things going unwell definitively.

"Controlling one hundred prostitutes with voodoo, a (weakness)** pimp..."

You need to improve the structure and grammar, At the moment i have no idea what this is about aha x

I have to say this logline is a bit confusing you should try changing the words around.

"When a greedy madam use the power of voodoo to force young girls into prostitution, she must save herself when they unexpectedly turn into brain eating sex zombies."

Hope that helped, good luck with this.
