A possible concise summary is:
This is a transcript of a horror movie about a writer named Artur who goes to a remote cabin to finish his book. He finds a doll named Alfred that has a rule: feed him with 12 leaves every day or face the consequences. Artur ignores the rule and gets involved with a mysterious woman who turns out to be part of a cult that sacrifices writers to Alfred. Artur tries to escape but is captured and killed by the cult. The movie ends with another writer being sent to the cabin as the next victim.
