A psychology student has a theory to rid himself of his horrific childhood memories and returning to his small hometown he tests them out on his unsuspecting girlfriend, but when a bored local girl sets her sights on him as her escape from the town, it puts a cleaver into his plan.

Thanks Halli, leaving out the girlfriend had never entered my mind, but you're correct. Thanks for a new outlook to this agonizing process.
Thanks Adele93, thanks for you input too, it all helps.

Maybe it's ok to leave out the unsuspecting girlfriend and just focus on the guy and the local girl. Sounds interesting just a little confusing.

Not that I'm good in writing excellent loglines, but.. this one isn't really clear to me: who's the antagonist? The bored local girl?
