A great day for Borovia. King Otto having ordered a large dam built, now has to attend the ceremony to open it. The King is pleased that the dam was finished on schedule at half the cost but is a little unsettled to hear that the dam will not survive hurricanes or meteorite strikes. Meanwhile princesses Lucy and Loretta, whilst on a walk about with a group of nuns, get locked in a high tower. Send for help..send for the Big Knights....enter the Big Knights....enter a meteorite????

Mrs. Minion, Sir Boris and Sir Morris's house keeper decides to pay a visit to her sister in the neighbouring town of Borodzo. Sir Boris and Sir Morris have to fend for themselves in the kitchen with disastrous consequences for the Castle and an evil Imp that turns up to try and trick Sir Morris. Mrs Minion returns to save the day using a vacuum cleaner and prevents the boys from starving to death.

The Big Knights disgrace themselves whilst performing a song (and belching) at a banquet held by the King. He at first dismisses them from the order of Knights and banishes them but the boys are granted an appeal made on their behalf by the two Princesses. Sir Boris and Sir Morris are forced to attend the Borovian School of Chivalry (run by Sir Kiftsgate) where they are soon appalled at what new knights are taught (how to bow to a Duke and an Earl). The Big Knights decide to teach the old methods of fighting, eating and barking. Sir Kiftsgate is equally appalled when they suggest this. Hence our two heroes open up an Old Fashioned Knight School where the old arts are taught. Their new pupils, however, are not what they seem to be. Unknown to Sir Boris and Sir Morris they end up teaching Knightly secrets to Dragons, Witches and Ogres who eventually terrorise the kingdom until it is rescued by the Big Knights. Sir Kiftsgate, however, states that the Big Knights are indeed his finest pupils suggesting he taught them everything. This does not fool Princesses Lucy and Loretta or Wizard Zabobon for a moment.

Sir Doris's hamster wheel is squeaking. It has been squeaking all night keeping the entire castle awake. Sir Boris is determined to get it sorted and whilst he is busy, Sir Morris receives a strange visit warning him not to take the hamster wheel to a famous but mad scientist to mend. Sir Morris therefore forgets the warning and does the complete opposite and thus suggests to Sir Boris that they take the wheel to be fixed. On arriving at the mad scientist lab, chaos ensues and the boys end up changing history as they travel backwards through time.

Sir Boris and Sir Morris need a holiday and decide to check out the local tourist information centre. They are sold on a cheap package to a miserable dark village being terrorised by Vampires. Although warned off by the locals the boys eventually find themselves surrounded by Vampires in the Castle.

After hearing a bed time story Sir Morris swaps all of his and Sir Boris's gold for a worthless magic bean.

The village local games is an event to which the Big Knights always attend. This year, however, the locals are determined that Sir Boris and Sir Morris will not take part. The boys are thus sent off into a thick forest. The villagers soon regret their decision as Sir Boris and Sir Morris come across a witch and one their favourite sports is witch hurling.

King Otto hears that the Queen of one of his neighbouring Kingdoms has a sorceress who can turn any metal into gold. He thus wants the magic spell and requests two volunteers. Sir Boris and Sir Morris volunteer and are made invisible by King Otto's wizard. As usual things don't turn out the way they should and King Otto ends up poorer than when he began.

Sir Morris's pet Hamster wanders out of the castle in search of food. She soon goes missing and ends up in the stomach of a hungry dragon.

King Otto is alarmed to find that an error in the local finances has meant that a large sum of money has been paid to a local town for the construction of a clock. He thus sets off with the princesses Lucy and Loretta to see this fine time-piece. The local town's folk are very pleased with the clock and of the impending visit of the King. Their happiness is soon turned to dismay after the clock is destroyed by Sir Boris and Sir Morris when they are playing toss the rock. The Knights themselves thus decide that they will fix the clock.

King Otto, the princesses and an escort of knights are driving along the local road in Borovia (King Otto's realm) when they come across a Troll and his bridge. The Troll politely informs them that they must either pay a toll, solve a riddle or beat him in combat in order to pass over safely. The King refuses and attempts to cross by foot during which he is magically lifted up, turned over and dropped in the muddy river. King Otto then calls his knights to deal with the Troll. The Princesses keep on asking their father to pay the Troll the toll. The Troll grow to about 6 times his original size and so the knights back off. The King still will not pay and eventually has to call for the Big Knights assistance. They arrive and introduce themselves to the Troll who now grown 8 times his size and a fight begins. Neither side wins as both the Troll, Sir Boris and Sir Morris are exhausted. The King then agrees to try and solve the riddle. This is eventually solved by the Big Knights who can then cross over the bridge. Everyone else now pays the toll to go over the bridge...except King Otto who instructs his wizard to take the magic spell off the bridge. Once the spell has been removed, King Otto's car moves over the bridge which crumbles into the muddy water.

King Otto as usual is dreaming of wealth and power. He learns of a new cheap power source and against the advice of his scientists, he invests in dangerous but cheap form of power for Borovia. Will our two heroes save the day and cause havoc as they try to help....Enter the Big Knights.

When King Otto's fearsome sisters send word that they wish to entertain their nieces, Lucy and Loretta, Sir Boris and Sir Morris volunteer to escort the princesses to their aunts' distant castle whereupon they experience a peculiar feeling.
