Nightwing

“The day belongs to man. The night is theirs.”

Livestock start dying on an Arizona Indian reservation, and then people do too, the bodies marked by bites no one can place. Youngman Duran (Nick Mancuso), a tribal deputy, runs into Phillip Payne (David Warner), a bat hunter who arrives certain of what is out there. Arthur Hiller sets them against a night that belongs to the colony, with the reservation and everyone on it left to whatever the dark brings.
