Stephen Fry has lived with bipolar disorder for decades, and here he sets out to talk with other people carrying the same diagnosis, from ordinary sufferers to public figures willing to describe what the highs and lows actually feel like from inside. The film treats manic depression as a condition still widely misunderstood despite affecting an estimated two percent of the population, and Fry uses his own history with it to get past the guarded answers people usually give doctors or journalists. Conversations move between the euphoric highs, the productivity and confidence they bring, and the crashes that follow, including the risks of hospitalization and suicide that come with the illness. Fry's presence changes the register of these interviews: he is asking as someone who has been there, not observing from outside. The result is less a clinical explainer than a series of honest accounts of what it costs to live with a mind that swings this hard, and how little the outside world tends to see of it.
