premise: Love in the Ring (German:Liebe im Ring) is a 1930 German sports film directed by Reinhold Schünzel and starring Max Schmeling, Renate Müller and Olga Tschechowa. Schmeling was a leading German boxer of the 1930s, and the film attempted to capitalise on this. Schmeling later appeared in another boxing-themed film in "Knockout" (1935).
hypothesis: Love in the Ring is a 1930 German sports film that is kick boxing-themed.
reason: "Kick" boxing was definitely not a thing at that time, and the actual film was definitely not about kick boxing. I believe "kick" fooled the AI system.
