Mainstream Tickle Torture [MM/F]

Hello,

i´ve got a question:

i am looking for an old german movie from 1983, which is called: "Liebe lässt alle Blumen blühen" (french title: "L'attrapeur");

the director of this german movie is Marco Serafini and its based on a novel from Heinz G. Konsalik (written in german);

the name of the tickled actress ist Beatrice Kessler and she is interrogated by two men in a tent;

can anyone help to find the movie / clip?

thank you very much - it seems to be a good scene;
