David Mitchell hosts the panel game in which four comedians are encouraged to tell lies and compete against one another to see how many items of truth they’re able to smuggle past their opponents.

Tony Hawks, Lucy Porter, Zoe Lyons and Justin Edwards are the panellists obliged to talk with deliberate inaccuracy on subjects as varied as divorce, lying, Mexicans and coffee.

The rules are a mixture of "pure simplicity and unnecessary complication". Each edition of the show consists of a panel of four people. Each member of the panel gives a short lecture on a particular subject. However, the lecture they give is complete and utter fabrication... except for (normally) five seemingly weird and unbelievable truths which they must mix in. The lecturer has to try and smuggle these truths into their lecture in such a way that the listening panel don't spot them.
