Leaving behind a lucrative career voicing radio commercials, Alan Partridge makes a bravely personal and personally brave return to television - to make Britain's first ever documentary about mental health.

Continuing his quest to fix the nation's mind, Alan posits a question - does talking help or is it better to just shut your mouth? - and uses it to help the meek speak.

Hosting Saudi radio alone in a Norwich business park prompts Alan to ask the question: Is solitude healthy or do we need other people? Can dogs or technology fill the void?

Can nature heal a troubled mind? Alone in the Peaks with only a stick-cam, Alan draws on the teat of Mother Nature and unlocks a heroic side some people doubted he ever had.

Newly single and never happier, Alan throws himself into new experiences to see if trying fresh things can improve our wellbeing - and finds joy in the unexpected.

Finding himself back where he began, Alan is forced to wonder if he's come full circle or gone nowhere - before a tragic death leads to a moment of quite staggering catharsis.
