Blood Red Sky (also known as Transatlantic 473) is a 2021 action horror vampire film directed by Peter Thorwarth, who co-wrote the screenplay with Stefan Holtz.

At the airport, Elias befriends a man named Farid, while his mother takes medicine that causes her severe discomfort.

As the passengers settle down for the evening, a group of men, including the co-pilot Bastian, murder the sky marshals and sabotage the black box, preventing the plane from being tracked on radar.

Assuming she is dead, the hijackers force Farid to record a statement that makes it appear the plane has been seized by Islamic terrorists for a suicide attack, knowing it will be shot down.

Nadja accesses the cargo hold, removes the contacts and dentures that conceal her mutated eyes and fangs, and feeds on a dog.

He subdues her with UV light and extracts her blood, but as he is about to stake her, Elias accidentally depressurizes the plane with Berg's gun.

The website's critics consensus reads, "Blood Red Sky makes the most of its high-concept vampire story, delivering a fast-paced treat for genre enthusiasts."

The audience consensus reads, "Blood Red Sky has a great idea for a horror movie, even if it's quite a bit slower than its cool setup might suggest.
