Frank and his team want to give something back to the East End public who have supported the market through thick and thin. What better way than to put on a charity auction with the stalls offering up a complete mixture of wares? Meanwhile, an inventor arrives at the market with a celebratory product he designed himself, and we meet Billy the eternal optimist, who sells headstones and memorials.

Market boss Frank is taking a rare day off, and for Dean, one of the managers, it represents a big opportunity - but everyone knows that whenever Frank puts his feet up, everything tends to go wrong. Meanwhile, a newcomer to the market arrives with an array of games he designed and built himself.
