The film is a dark comedy of manners that explores the life of a Berlin school teacher and the contrasts between his public and private lives.

Taxi zum Klo was considered groundbreaking for its subject matter and achieved a cult status among audiences of the time.

[2][3] Frank (all characters are named after the respective actors), known to his friends as Peggy, is a teacher and Bernd works in the cinema.

Bernd prefers a quieter life and wants a farm, while Frank, on the other hand, is looking for adventure, longing and testing his limits.

At the Berlin drag ball, which Bernd attends as a sailor and Frank as an Arabian dancer in tulle, things escalate between the two.

Chaos erupts, and Frank realises his life is at a crossroads: go back to Bernd, commit suicide, or carry on as a single guy.

[4] In an interview he later said of his motivation for making this film: "I was not pursuing any political goals, but rather realizing purely private interests: my career as a teacher was ruined.

The ironic film, which was also perceived as a comedy by some audiences, is remarkable above all for its openness in its portrayal of gay sexuality,[a] which was unmatched then and still is today.

It is the only non-pornographic film in Germany, Austria and German-speaking Switzerland, approved for audiences aged 16 and over, with a scene in which not only fellatio can be seen, but also ejaculation into the partner's mouth followed by swallowing semen in a long, detailed close-up.
