Actor, comedian and broadcaster Stephen Mangan presents a comedy chat show about shame and guilt.

Each week Stephen invites a different eminent guest into his virtual confessional box to make three ‘confessions’. This is a cue for some remarkable storytelling, and surprising insights.

We’re used to hearing celebrity interviews, where stars are persuaded to show off about their achievements and talk about their proudest moments. Stephen isn’t interested in that. He doesn’t want to know what his guests are proud of, he wants to know what they’re ashamed of. That’s surely the way to find out what really makes a person tick. Stephen and his guest reflect with empathy and humour on why we get embarrassed, where our shame thresholds should be, and the value of guilt.

This week, comedian Lucy Porter apologises for a youthful indiscretion, discusses the disadvantages of PVC and reveals a secret as yet untold.

Other guests in this series include Cariad Lloyd, Dr Phil Hammond, Clarke Peters, Suzi Ruffell, Marian Keyes, Phil Wang, Joan Bakewell, Nigel Planer and Alastair Campbell.
