Friend of the World (2020)

Diane (Alexandra Slade) awakens in a bunker surrounded by dead bodies after a brutal massacre. After attempting to escape the structure, she eventually passes out at the bottom of an elevator shaft where she is rescued by a mysterious man who calls himself General Gore (Nick Young).

Though he plays mind games with her, Gore gives her food and water as he attempts to figure out who Diane is and how she got into the bunker. Still shaken, she has trouble piecing it together, but she can remember being taken there by force. She also tells him about the film she had been creating.

Gore hints at a contingency plan for escaping the bunker. Without a good alternative, Diane decides to follow him through the toxic environment in hopes of reaching safety. Along the way they are attacked by mutating creatures that were allegedly poisoned by radiation. A tension and psychological confrontation slowly develops between the two survivors as they get nearer to their destination and Diane feels her sanity start to slip.
