After a customer accidentally drops a £5 note in the pub, it embarks on a whistle-stop tour of local businesses. Passing through the hands of a tobacconist, a garage owner and even a dentist, it finally finds its way back to to the bar till. The customer rushes back to reclaim it, relieved that the fake note has not gone into circulation, unaware that it has kept the local economy going in the meantime. Filmed in Barkingside, Ilford, scenes feature local streets and businesses.
