Monolith (2022)

The central character (known only as The Interviewer) is a disgraced journalist who, depressed and alone in her parents' large home while they are away, takes up podcasting about unsolved mysteries in the hopes of reviving her career. She invites listeners to phone in with their stories. A story begins to build around a strange black brick, first reported by a maid named Floramae, and followed by many others who report the mysterious appearance of a similar object in their lives.

The story is simple, but anxiety and tension is built further with the introduction of a German art collector, Klaus, who has a collection of the bricks, and has had them scanned and analysed.

The Interviewer's mental health declines as the story proceeds, and after she comes to the startling realisation that she herself is involved in the backstory of one of the bricks, the final scenes leave their interpretation open to the audience.
