Plot synopsis:
Part I — The Great Gambler: A Picture of the Time (Part I - Der große Spieler: Ein Bild der Zeit)
Dr. Mabuse is a criminal mastermind, doctor of psychology, and master of disguise, armed with the powers of hypnosis and mind control, who oversees the counterfeiting and gambling rackets of the Berlin underworld. He visits gambling dens by night under various guises and aliases, using the power of suggestion to win at cards and finance his plans. Among his many henchmen are: Spoerri, his cocaine-addicted manservant; Georg, his chauffeur and sometime assassin; Pesch, an inept goon; Hawasch, who employs a gang of blind men in a counterfeiting operation; Fine, a woman who serves as a lookout; and Folies Bergère dancer Cara Carozza, who loves him.
As the film opens, Mabuse orchestrates the theft of a commercial contract in order to create a temporary panic in the stock market, which he exploits to make huge profits.
Edgar Hull, the son of a millionaire industrialist, becomes Mabuse's next victim. As "Hugo Balling", Mabuse gains access to Hull's gentlemen's club and wins a small fortune at cards from the hypnotized Hull, who is made to play badly and recklessly. Afterwards, Hull is unable to account for his behavior.
State prosecutor Norbert von Wenk takes an interest in Hull, believing he is the latest in a string of victims similarly tricked by the elusive "Great Unknown". Von Wenk goes undercover at a gambling den, where he encounters a disguised Dr. Mabuse. Mabuse attempts to hypnotize von Wenk, but he effectively resists. Mabuse flees. Von Wenk, quickly regaining his faculties, gives chase through the city, but the doctor escapes. Boarding a taxicab driven by Georg, von Wenk is gassed, robbed, and set adrift in a rowboat.
Dr. Mabuse realizes that Hull is assisting the state prosecutor, and resolves to eliminate both men. Carozza, who has been romancing Hull on Mabuse's orders, lures the young man to a new illegal casino; when von Wenk calls in the police to raid the place, Carozza, Hull and a police bodyguard exit through the back door, where Georg awaits. He kills Hull, but Carozza is caught and jailed. Von Wenk questions her for information about the "Great Unknown", but she refuses to speak. Von Wenk enlists the aid of Countess Told (nicknamed the "Passive Lady"), an aristocrat bored by her dull husband and seeking thrills wherever she can find them, to try to get the information by trickery. The Countess is placed in the same cell, an apparent victim of another raid, but Carozza is not fooled. Carozza reveals only her great love for Mabuse, ensuring her silence. The Countess, moved by Carozza's passion, tells von Wenk that she cannot continue to assist him.
Dr. Mabuse does nothing to extricate Carozza from jail. He instead attends a séance where he meets Countess Told, who (while under his hypnotic influence) invites him to her house. Once there, Mabuse, taken by the Countess's beauty, decides to display his power by telepathically inducing her husband, Count Told, to cheat at poker. His guests are outraged when they detect it, and the Countess faints. Dr. Mabuse uses the distraction to abduct her and imprison her in his lair.
Part II — Inferno: A Game for the People of our Age (Part II - Inferno: Ein Spiel von Menschen unserer Zeit)
A sick and disgraced Count Told seeks the help of Dr. Mabuse to treat his depression; Mabuse uses this chance to isolate the Count in his manor and cut off any inquiries about the Countess's whereabouts. The Count's condition worsens, and he is tormented by hallucinations.
Meanwhile, Carozza is moved to a women's prison and again interrogated by von Wenk. Fearing betrayal, Mabuse sanctions Carozza's death. Georg smuggles poison to her cell, which she takes out of loyalty. Another of Mabuse's henchmen, Pesch, bombs von Wenk's office while posing as an electrician, but von Wenk is unharmed and Pesch detained. Mabuse – again fearing betrayal – arranges for Pesch to be killed by a sniper while being transported in a police wagon.
Intent on leaving town, Mabuse gives the captive Countess the choice of going with him voluntarily. Her refusal angers him, and Mabuse vows that he will kill the Count. Through his powers of suggestion, he induces the Count to commit suicide with a razor blade. When von Wenk investigates his death, he questions Dr. Mabuse as the Count's psychoanalyst. Dr. Mabuse speculates that the Count had fallen under the control of a hostile will, and asks von Wenk if he is familiar with the experiments of one "Sandor Weltemann", who will be performing a public demonstration of telepathy and mass hypnosis at a local theater.
Von Wenk and his men attend Weltemann's show. Weltemann is none other than Mabuse in disguise, and his magic show provides him an opportunity to hypnotize von Wenk, who falls into a trance. Mabuse's secret command to von Wenk is to leave the auditorium, get in his car, and drive off a cliff, but von Wenk's men intercede just in time. Coming to his senses, von Wenk orders a siege of Mabuse's house.
Dr. Mabuse and his men make a final stand. In the ensuing gunfight, Hawasch and Fine are killed, Spoerri and Georg are taken into custody, and the Countess is rescued. Dr. Mabuse flees through an underground sewer to Hawasch's counterfeiting workshop, where he becomes trapped, as the doors cannot be opened from the inside. There, Mabuse is confronted by the ghosts of his victims and various demonic illusions.
Spoerri, under interrogation, identifies a key found at Mabuse's mansion as being for the workshop. Von Wenk and the police break in and take the now-insane Dr. Mabuse away. In Das Testament des Dr. Mabuse (The Testament of Dr. Mabuse, known also as The Last Will of Dr. Mabuse) it is revealed that he is confined to an insane asylum.
