The Drowned (2022)

"The Waters Are Rising"

A lone survivor wakes up on a rocky, empty coastline. With a mysterious orb guiding her, she searches the landscape for food and shelter, looking for signs of civilisation, people, anything. Finding only the crumbling remains of buildings long deserted, she becomes increasingly fearful of the reality of her situation, and when the orbs' final destination is revealed, she must come to terms with a fundamentally changed world.
