In the film, Brandt is a member of SPECTRE, a global criminal organization led by Ernst Stavro Blofeld. Her mission is to infiltrate a US spacecraft and capture an astronaut in order to provoke a war between the United States and the Soviet Union.

Brandt initially appears as a seductive figure who attempts to assassinate Bond by luring him into a bedroom and setting it on fire. However, Bond manages to escape and later confronts Brandt during a fight scene in which she tries to kill him again.

Ultimately, Brandt's failure to complete her mission leads to her being punished by Blofeld, who drops her into a pool of piranhas as a form of execution.

Helga Brandt is often remembered as a memorable and iconic villainess in the James Bond franchise. Her character's seductive nature and lethal abilities make her a formidable opponent for Bond, and her demise at the hands of Blofeld is seen as a shocking and memorable moment in the film.
