Ariadne is a writer and mother embroiled in an affair with a married man. At the core of her current manuscript is the need to understand what it means to say 'I love you.' To make ends meet while writing, she joins a research study in which she’s paid to live with an AI device called Dirk. Capable of mapping Ariadne’s brain, Dirk calls into question issues of privacy and consciousness: how we communicate thoughts, what it means to embody our desires, and whether we ought to act on them.
