Baron Oslow (David Davies) murders the Earl of Steyne and steals his identity. The Juggler Ali (Michael Peake) overhears him plotting with the Sheriff to sail to the Holy Land and kill King Richard. Ali is also killed. Ali's partner Sybella (Soraya Rafat), who has an amazing memory but can hardly speak English, tries to warn Robin. However, it is Maid Marian who falls foul of the false Earl of Steyne.

Note: Although Robin's dialogue refers to Ali as a Juggler, it is clear that he is meant to be a Jongleur, as he performs magic tricks in the episode, and no juggling.

Re-intro for Will Scarlet (Paul Eddington). Will returns with a Lady Maud (Geraldine Hagan), daughter of De Sarigny, in tow and an advanced Saracen crossbow that can outshoot a longbow. Accused of kidnapping, he is captured by the Sheriff and sentenced to hang. Scarlet bargains for his life by demonstrating the crossbow. Marian informs Robin and he believes the Sheriff plans to double cross Scarlet.

Sir Nigel (John Carson), Lady Marian's cousin, returns from the holy land with two friends and intends to marry her to obtain her land. Discovering Marian is in league with the outlaws, he threatens to expose her to the Sheriff unless she agrees to marriage. Robin and Sir Nigel's friends have to convince the Sheriff that he is mentally unbalanced with the fever.

Sir Geoffrey (Basil Dignam) returns from the Crusades and finds the Sheriff has moved the stream that forms the boundary marker of his estate, so that his land now forms part of the Sheriff's own land. The Abbot is displeased with Friar Tuck's lack of alms collected so Tuck arbitrates the dispute on Love Day, a day in the year when ecclesiastical law takes precedence, for a fee, while Robin and Will Scarlet breach a dam.

Note: This episode, apart from three or so studio scenes, is shot almost entirely on location.

Lord Giles (Anthony Jacobs) arrives in Nottingham to uncover tax evasions. To avoid more tax problems, the Sheriff puts forward a plan to have the eccentric Lord Eilmar (Arthur Howard) accused of being a sorcerer, and his lands given over to Lord Giles. Marian tries to help, but Eilmar is arrested and Robin comes to his aid, and the eccentric Lord's interest in flight comes to Robin's aid as a kite.

A boy steals a loaf of bread from the Sheriff's men. Friar Tuck gives him sanctuary in the local church, but after 40 days, under the law of sanctuary, the boy will have to leave the country. The Sheriff demands 500 loaves to free the boy by the next midday. Robin devises a plan to obtain the Sheriff's supply of flour to fulfil the demand.

Intro Sir Alan-a-Dale (Richard Coleman), who is unaware that Prince John has accused him of murder and declared an outlaw. In warning Sir Alan, Marian is wounded by a crossbow bolt, threatening to reveal her identity to the pursuing Sheriff.

Opening scene: Song by minstrel Sir Alan-a-Dale with harp: "The sign of the Blue Boar, hangs beyond the door; the serving girl called Joan, has left me to drink alone!"

The Sheriff of Nottingham is preparing to leave for three months' duty in London. Sir Alan-a-Dale (Richard Coleman) is missing from Robin's camp and presumed held captive by the Sheriff. Robin and Will Scarlet intercept the Deputy Sheriff and free a prisoner, the mysterious Ralph of Plumtree, and he insists on impersonating the Deputy Sheriff to discover if Sir Alan is a prisoner. The Deputy Sheriff lays a trap for both Robin and Marian.

Note: Last appearance of the Sheriff of Nottingham (Alan Wheatley) and intro of the Deputy Sheriff (John Arnatt).

Little John returns to Sherwood Forest and finds his place in Robin's band taken by Will Scarlet. The Deputy Sheriff offers Little John a pardon.

The Deputy Sheriff tells Robin, during a truce, that he will hang two serfs everyday until Robin gives himself up. Robin calls on Marian's guests, two lords who outrank the Deputy Sheriff, Alford (Humphrey Lestocq) and Beaumont (Jack Melford) to make the Deputy Sheriff show his true colours by dressing them as serfs and hanging them first.

The Deputy Sheriff's is attacked and his chain of office stolen in Lower Fitzwalter, a village of freemen. At the blacksmith of William (Kevin Stoney) hue and cry is invoked under the rule of Frankpledge and, if the attacker cannot be found, nine men will hang. Robin, Marian, her maid Jenny (Geraldine Hagan) who had teased Dick (Ronald Hines) the Swineherd, the thief, provide the solution.

Sir Geoffrey (John Carson) and his serf Herbert (Leslie Phillips) pose as outlaw Jim Stark and his lieutenant to join Robin's gang for information on the outlaw life for Sir Geoffrey's journals.

The Deputy Sheriff tries to turn the Archbishop (Carl Bernard) against Friar Tuck, implicating him with the outlaws. Tuck takes an oath in front of the Archbishop not to reveal the identity or the location of the Sheriff's latest prisoner, an envoy of King Richard, about to be hung and Tuck cannot break his oath and tell Robin to save the man, so he calls a special service at the church.

A former Crusader friend of Robin's, Martin (Brian Rawlinson), who saved his life seven years before at the crusade, masquerades as one of Robin's gang and begins robbing travellers entering Sherwood forest, including Friar Tuck, and fatally wounding John Dale (Terry Yorke) in his home. Martin wants to join Robin's band. When Martin learns Friar Tuck and Marian know Robin, he has the upper hand. Robin has to make him leave, bearing in mind the debt he owes this man.

A charm peddler named Hugo (Victor Maddern) arrives in Nottingham. Lady Marian takes against him for getting the locals to waste their money on his phoney potions. She gets the Deputy Sheriff involved to arrest Hugo. Robin, at the behest of Friar Tuck, disguises himself as a fellow con-man to investigate the peddler's activities and finds himself rounded up with the charm peddler in the Sheriff's dungeon, both to be hanged, to Marian's horror.

Duncan of Stoneykirk (Hugh McDermott) makes a return visit to Sherwood forest, still with an eye for Marian, only this time he has a plan to win a bagpiping contest against Tam McKinnon (Andrew Downie) at the castle of Sir Fulke (Patrick Troughton), or so he claims. Robin, dressed in highland garb and beard, accompanies him. Duncan's intention is revealed, although Duncan is wounded in the process.

Still hanging around Robin's camp, Duncan turns his attentions to the Lady Marian until his lassie Jessie (Ellen McIntosh) arrives to take Duncan back home. With Duncan refusing to leave Robin, Robin tries to woo Jessie to make him jealous, but it is Marian who is jealous. Robin arranges an archery contest between Marian and Jessie for five gold crowns to set Duncan on the road to Scotland.

Will Scarlet witnesses the murder of an envoy. He and Robin capture Wilfred (Michael Ripper) who had led the envoy into the trap. They discover that the killer was Sir Hartley (David Davies) who intends to kill Constance, Duchess of Brittany (Patricia Marmont) and Prince Arthur (Jonathan Bailey) as they pass through Sherwood to Northumberland.

Little John acquires 'The Pharaoh Stones', stones that predict the future, from a peddler (Carl Bernard), and falls under their superstitious influence. The band is also convinced. Robin devises a plan with Will and Marian to break their spell, but it leads to Little John's capture.

To avoid capture by the Sheriff, Robin is forced into a proxy marriage, performed by Friar Tuck, to Judith Denton (Mary Mason), the daughter of wealthy merchant Master Bligh Denton (John Horsley) who mistakes Robin for her real suitor Sir Peter Marston (Nigel Davenport).

Friar Tuck's twin brother Edgar returns to Nottingham. The Deputy Sheriff imprisons Tuck and forces his brother Edgar to impersonate him, for the purpose of confessing his brother's 'sin' (of aiding Robin) and denouncing Maid Marian to the Bishop (Charles Lloyd-Pack). Robin has to match the Deputy Sheriff's duplicity by capturing the Bishop and the Sheriff.

Robin becomes the latest victim of Sir Hugo DeBask (Laurence Hardy), a lord who arrests travellers through his estate and sets them to work on his lands if they can't pay the fine he imposes at their trial. Looking for him, Marian also falls into the trap. Escape comes from an unexpected quarter.

Note: Laurence Hardy's character is incorrectly billed as Sir Marmot on the end titles.

Marian has been informed by the Deputy Sheriff that her father has died in the Holy Land and Prince John has nominated Sir Guy Quentin (John Horsley) to take over her estate. Friar Tuck informs Marian her father is alive and she can appeal to the courts. Marian's sixty-year-old uncle Sir Percy (Jack Allen) pre-empts this by challenging the much younger Quentin to a duel and Robin has to convince Quentin that Sir Percy is a fearsome fighter.

Boland (Michael Gough), a former Crusader, defeats Will Scarlet and then Robin Hood in a sword fight and is only prevented from killing him by Maid Marian's prowess with the bow. Boland offers his services to the Deputy Sheriff, who makes him his lieutenant and takes sword-fighting lessons so he can kill Robin Hood himself and take the glory and become Sheriff. Robin Hood accepts the challenge in the hope of revealing the Deputy Sheriff's true colours.

While Lord Ambrose is away at the Crusade, Sir Watkyn of Parstock (Harry H. Corbett) his bailiff, has been extorting heavy taxes from the tenants and serfs on his estate with menaces. Friar Tuck seeks Robin's help, but is arrested as an outlaw. Robin contacts Father Ignatius (Philip Latham), Lord Ambrose's priest, and with his aid puts paid to Watkyns' underhanded schemes.

Needing to win an archery tournament against Lord Repton (Richard Caldicot), the Deputy Sheriff parleys a truce with Robin to be his archer for the day. His opponent is Mark Crispin (Derek Tansley), champion bowman of England.
