After hearing a child screaming for help from the green depths of a vast field of tall grass, Becky, a pregnant woman, and Cal, her brother, park their car near a mysterious abandoned church and enter the field, discovering that they are not alone and, for some reason, they are unable to escape a completely inextricable vegetable labyrinth.
In the Tall Grass

Elsa and Clive, two young rebellious scientists, defy legal and ethical boundaries and forge ahead with a dangerous experiment: splicing together human and animal DNA to create a new organism. Named "Dren", the creature rapidly develops from a deformed female infant into a beautiful but dangerous winged human-chimera, who forges a bond with both of her creators - only to have that bond turn deadly.
Splice

A group of strangers find themselves trapped in a maze-like prison. It soon becomes clear that each of them possesses the peculiar skills necessary to escape, if they don't wind up dead first.
