I've seen it before and highly recommend it: It shows trainings and bout scenes, sound bites from rikishi and other people in the sumo world, as well as slices of everyday life in a heya. We see Goeido, injured but still strong, while the sequences with Ryuden and his then fiancee may be a piecec of historical interest.
The film comes with a content warning concerning alcohol and nudity. While we indeed see people consuming alcohol, the degree of nudity is within the usual in pro sumo.
