To get out of cleaning the loft with Dad and Adam, Jonny claims to have dislocated his shoulder. But when Adam discovers he’s lying, he threatens to tell mum immediately. “Fine,” says Jonny, ‘”Then I’ll just tell her all the grotty details of what you got up to with Hayley Posner”. Adam is horrified. Hayley was Adam’s blind date, who he slept with and then never called back, “because she smelt like mum”. Mum mustn’t find this out, so Adam has to let Jonny get away with his pretend bad shoulder. Meanwhile Mum and Dad are not on speaking terms. There’s been a terrible argument. Dad tells the boys that the reason – much to their horror – is ‘sexual’. But what exactly he got up to, no one will tell them. Mum’s best friend – Aunty Val (Tracy Ann-Oberman), comes round for dinner to lend mum moral support, as mum’s argument with Dad escalates.What is mum and dad’s terrible secret? And will mum and dad find out all about Jonny and Adam’s secrets too? All this, and a visit to the unfriendliest pub in the world – The Black Boy
