A frustratingly not-terrible action thriller.
"Taxi zum Klo" is an unsparingly honest film, documentary matched with (I assume) docudrama, in which Ripploh reveals himself fearlessly. The revelations that must have taken the most courage are not the ones about his homosexuality, but the ones about his unhappiness, his sense of inadequacy. He appears in this film to be seeking a life of openness, love, beauty and loyalty to a lover -- and at the same time he marches on a treadmill of futile promiscuity.
As the film opens, Ripploh is a schoolteacher in West Germany. He seems to be a pretty good teacher, cheerful and frank with his students. After hours, he cruises the gay bars and public meeting places, seeking anonymous sex, often with a sadomasochistic flavor. He's particularly drawn to gay sleaze, to the bars specializing in the theatrical flaunting of sexual identity, to the places in the big city where sex is mixed with danger.
He meets a young man, Berndt, whom he values more than most of his partners. They become lovers. They move in together, and Ripploh tries to break his pattern of addictive sex and to be faithful to one person. The movies best scenes involve Frank and Berndt trying to work out the ground rules of a relationship.
Meanwhile, Ripploh gets fired from his job (for staying out too late after a drag ball and imprudently turning up in his classroom in drag). He contract hepatitis, is hospitalized, and, in the movie's saddest scene, leaves the hospital bed in his patient's gown, and hails a taxi to take him to a rendezvous with an anonymous stranger (hence the title's English translation, "Taxi to the Toilet").
