In 1986, Alastair Campbell had a mental breakdown, the culmination of months of intensive stress at work, too much alcohol, and myriad complex issues. Campbell believes that speaking openly about mental illness helps to de-stigmatise it and so in this startlingly frank documentary he relives the traumas of his breakdown. He talks to some of those who witnessed it, and though it was more than 20 years ago, the journey opens up painful memories. In the end Campbell believes the experience left him stronger and able to cope with the stresses and strains of working at the seat of power.
