In medieval England, many years have passed since Robin Hood was robbing from the rich and giving to the poor. A new tyrant, however, named Duke Simon Des Roches (David Farrar), is poised to seize control of the kingdom. To stop him, the remaining Merry Men must rally to save their fellow countrymen. Needing a fearless leader, they call upon Robin's son Jamie (David Hedison). But the arrival of Deering (June Laverick), a girl who claims to be Robin's daughter, complicates matters.
