On a windy evening in Budapest, police Captain Karl Torok meets with his superior, the prefect of police, who has just lost the position of president of the cabinet to Torok's friend since childhood, Count Peter Alvinczy. As thunder and lightning begin, the countess Madalaine's first husband, Paul Szegedy, who everyone thought had committed suicide, calls her and threatens to create a scandal that will ruin Peter's career unless she comes to his room at the Hotel Orient. After she agrees, Lisa, her maid, tells Peter about Szegedy's threat. At the hotel, as Szegedy packs to leave, his mistress and vaudeville partner, Katherine Szabo, pleads with him to stay. Professor Omega, a self-proclaimed mystic with whom Katherine toured before she met Szegedy, overhears their conversation and then warns Szegedy of disaster evidenced in a fearful vision of thunder in the night. Katherine goes to the police station across the street from the hotel and asks that they stop Szegedy from leaving her.
