Nobody Sleeps in the Woods Tonight (Polish: W lesie dziś nie zaśnie nikt) is a 2020 Polish supernatural horror slasher film directed by Bartosz M. Kowalski, written by Kowalski, Jan Kwieciński, and Mirella Zaradkiewicz, and starring Julia Wieniawa, Michał Lupa, and Wiktoria Gasiewska [pl].

Thinking someone is trapped down there, the postman makes his mistake when he rips off a board barring the entrance and enters the basement.

The main protagonists all end up in a group together and head off into the woods with counselor, Iza, for a three-day hike.

The group reaches the house seen at the beginning of the movie and discovers the basement with Daniel's mangled body inside.

Zosia and Julek escape through a cellar window, but Iza stays behind to fight the monster to try and get Daniel's phone to call for help, which ends in her death.

Aniela and Bartek are talking by the lake when she is suddenly killed by a metal bar going through the back of her neck and mouth.

The following night, a black fluid seeps from the rock and enters the bodies of the twins, who lose their minds and become animalistic carnivores.

Seeing a body on the road and wanting to help despite Zosia's warnings, the officer is killed after failing to use his pistol against the murderer.

A monthly magazine Kino reported that the movie landed in the top 10 list of the most-watched films on the platform.
