Prague in the 1860s: Balduin is a popular, handsome student, the best fencer in town, in amicable rivalry with his friend Dahl for the affections of Lydia, the innkeeper's niece. While the students are celebrating Lydia's birthday, the opera singer Julia Stella arrives at the inn - and Balduin's life begins to unravel. He is immediately infatuated with the glamorous singer - but she is already kept by an admirer, the wealthy and foppish Baron Waldis. How can a poor student hope to compete? The mysterious Dr. Carpis, who also has ties to Julia and is jealous of the Baron, intervenes. But the price will be higher than Balduin can ever imagine. He risks his sanity and his life - perhaps his very soul - haunted by his own reflection.
Two young officers, Saint-Avit and Morhange, get lost in the desert and find themselves prisoners of the beautiful Antinéa, queen of the city of Atlantis. Saint-Avit, blinded by his love for her, obeys her when she orders him to kill his comrade... With L’Atlantide, Pabst offers a psychoanalytic reading of Benoit’s novel, with a dominant female figure who enslaves her lovers before destroying them. The film’s fantasy dimension is disturbing, L’Atlantide bathes in a humid nightmare atmosphere, between the desperate search for a missing friend and the apparitions of an underworld lost in the desert. A long, discursive flashback suggests the Parisian origins of Antinéa, born from the marriage between Clémentine, a pretty, light-thighed French Cancan dancer, and an Arab prince seduced during a theatrical performance. But again, it's impossible to know whether these are the ramblings of an old alcoholic or the strange truth.
