A heat wave hits Nottinghamshire and, when Prince John blocks all the local wells, the outlaws are forced to take desperate measures to save those at risk. Prince John discovers Robin and Isabella's secret relationship, and orders Gisborne to dispose of them, telling him that if he completes the task he will be made the new Sheriff.
