Stacey takes five teenagers to do work experience in a vast salad farm in north London. The five find themselves among the cucumbers in 35 acres of greenhouses during one of the hottest weeks of the year. Can they pick the perfect cucumber and get hundreds of them wrapped and packed ready to meet a succession of supermarket orders? It sounds simple enough! However, for some of the group, picking cucumbers, peppers and tomatoes is not their idea of fruitful employment and boss Vince is unimpressed with the work ethic on show. Stacey has to step in when a couple of the team discover the joys of trolley racing and cause damage to some of the tender plants.
