A local museum curator who is dipping her toe back into the dating pool is targeted by a charming serial killer. When a fateful romantic getaway between the two becomes a tense game of cat and mouse, both must confront the madness within him.
Maybe not a dead animal per se but the killer has a bad head wound and pulls something out of it and at first appears to be some sort of dying bird fetus. It is a hallucination but might be upsetting to some.
head is bashed in and they spend the second and third acts with a swollen eye. no permanent eye trauma that i can tell (but i also looked away a lot when it first happenedkl)
