The show was hosted by Sandra Studer from Switzerland, who was assisted by psychologist Werner Katzengruber. Politician Claudia Roth, director Dr. Dieter Wedel and actor Heiner Lauterbach took the personality test in the studio. Presenter Sandra Studer charmingly probed the celebrities when it came to questions about first love, fidelity and relationship killers. The answers were surprising and honest and family members and friends also had their say, confirming or denying the statements.

The psychologist Werner Katzengruber examined the statements of the prominent guests and at the end revealed which relationship types Ms. Roth, Mr. Wedel and Mr. Lauterbach are.
