Scarecrow

When high school teacher Aaron Harris escorts a group of delinquent students on a field trip, he didn't expect to encounter his old girlfriend Amanda. Some spilled blood revives an ancient monster which hungers for human flesh, and it chases the group through corn fields and abandoned farmhouses. Aaron and Amanda try to keep the students alive long enough to figure out how to defeat this seemingly unstoppable creature. When they finally finally realize that it only truly wants Amanda, they have to figure out a way to save the love of his life, and bury the Scarecrow once and for all.
