This one-off stand-up special is a performance of Simon Amstell's stand-up show, 'Numb', which he toured to sell-out audiences around the UK and Ireland in 2012, as well as Australia and, more recently, Los Angeles, San Francisco and New York. Recorded specially for BBC Four at TV Centre, it's a stripped-down, intimate performance, with no set and minimal lighting - a painfully raw, honest and deeply funny exploration of disconnection and loneliness.
