Okay, like I said, I haven't watched the miniseries, but German wiki actually has a summary of each episode, as first broadcast in 1973:
Part 1: (ZDF: January 1, 1973) King and Cadet
"I hear wonderful things about your mind. But it seems that you are spoiled," says Prussian King Frederick II at Königsberg University to Friedrich Freiherr von der Trenck, who is as intelligent as he is willing to duel. He asks the young man to be trained in the army. Trenck obeys. In Potsdam he soon proves to be the most talented cadet of all. Trenck will soon be promoted. In the beginning, Frederick II sees in him the friend of his youth Hans Hermann von Katte reborn. (Note by Selenak: this is not something Trenck, not suffering from modesty, claims in his memoirs. But I can see why the scriptwriter went for it - it provides as good a psychological explanation for the subsequent events as any. If Trenck did resemble Katte in whatever ways, it would indeed explain a lot..)
Trenck falls in love with Amalie, the king's sister. He gives Amalie a precious fan. But his love for Amalie is doomed. On the orders of the king, who dislikes the relationship between Amalie and the baron, Trenck is arrested. Note by self: We're not mentioning those anonymous letters and the business with the Austrians then?
Part 2: (ZDF: 7 January 1973) On the Run
On the orders of Frederick II, Trenck is held at the Glatz fortress. The king also forbids his sister Amalie from dealing with the rebel and plans to buy her into a nunnery as abbess. Amalie is deeply hurt. Note by self: Quedlinburg was indeed a Protestant nunnery of sorts, a "Frauenstift", but above all it was a source of income for unmarried high ranking female members of the royal family. Amalie didn't spend much time there, she was mostly at the court; when Fritz made her abbess, it was an acknowledgment she would never marry and provided her with an income beyond his own lifetime.
In Glatz, Trenck meets Lieutenant Nikolai, who is planning a desertion. The matter is revealed, Lieutenant Nikolai has to run a skewer, Trenck has to attend the punishment. When the commanding officer lets the already unconscious Nikolai drag through the alley, Trenck manages to push the captain off the horse, grab his swords and flee. He passes two guards in the fortress Of Glatz. Although he bravely and skilfully uses the weapon, he is caught again a short time later. After several failed attempts and a total of eleven months in prison at the Fortress of Glatz, Trenck manages to break out. After an adventurous escape, he finds shelter at the castle of Baroness Lazar in Bohemia, which is already known to him. Women have little resistance to the charm of the young daredevil. The way to Vienna to his cousin, the Pandurenoberst, is open to him.
Part 3: (ZDF: January 14, 1973) The Pandur Friedrich von der Trenck meets his cousin in Vienna, who is feared under the name Trenck der Pandur because of his unbridledness. The Pandur Franz von der Trenck enjoys the most miserable reputation imaginable. He is simply regarded as a murderer. Friedrich also feels something of this bad reputation when he points out his relationship with Baron Franz von der Trenck in Vienna. He learns that his cousin has now clashed with the top army leadership and is expected to face a highly distressing trial for bribery and other offences. The Pandur not only scolds his Prussian cousin in the worst possible way, he even lets him be ambushed by two friendly officers. When Friedrich fights back, he is arrested. He can only save himself by fleeing to Russia quickly.
Part 4: (ZDF: January 21, 1973) Baron von der Trenck can make his way to Moscow. He enters the Russian service as a riding master. At the Russian court, he falls in love with Anuschka of Lieven and also has a relationship with Anastasi Bestuscheff, the chancellor's wife. When he is found, he is tried to be suspected of counterfeiting coins. Trenck can justify himself, but he has to leave the Russian court. He settles down in Austria, where after the suicide of his cousin a large fortune is to wait for him. Note by me: not a suicide in Trenck's memoirs.
Part 5: (ZDF: January 28, 1973) In the Trap His cousin's inheritance turns out to be an evil trap. The late Pandur Franz has run 63 asset trials alone. The Austrian state bureaucracy is trying by all means to prevent Trenck from owning the huge estates. One does not even shy away from an attempted murder. Things become dangerous for Trenck when he returns to Danzig because his mother has died. The Austrians intercept him with the help of a beautiful woman and deliver him to the Prussian king. Note by self: no Austrian handover happening in the memoirs; it's all Prussians who take him prisoner. I suppose the scriptwriter wanted to avoid Trenck looking dumb for entering Prussian territory despite a warrant on him in the first place? Trenck is chained by him.
Part 6: (ZDF: 4 February 1973) The Tomb Under the harshest conditions, Trenck is imprisoned in the Magdeburg fortress on the orders of Frederick II. On the floor of his cell, the Prussian king had a grave slab with a skull and the name "Trenck" walled in as psychological torture. But Trenck cannot be worn down despite iron chains on his hands and feet. He is still planning to escape from the gloomy dungeon, especially as help is offered from outside: Lieutenant Sonntag maintains the connection with Princess Amalie. But a well-planned escape attempt fails. It was not until 1763, at the end of the Seven Years' War, that the king ends the harsh punishment of his former favourite. We're not mentioning MT petitioning him to do this?
Trenck immediately settles down and begins to write open-hearted memoirs. He thus annoys the imperial court, flees to Paris, falls into the turmoil of the French Revolution and dies through the guillotine. Note by self: okay, the scriptwriters here really depart from both the memoirs and historical reality. Trenck didn't start to publish his memoirs until after he'd settled down in Aachen, where he married, made a living by Hungarian winen trade, and produced 13 children before going to France when he was already over 70; there was certainly no "fleeing" involved this time, as one of the possible explanations as to what the hell he was doing in revolutionary France was that he might have been spying for the Austrians (again) (though I really doubt it). I guess the tv show didn't want to make a time jump and show Trenck as an old man?
