That is essentially the gist of Keep. We are repeatedly told in rather uninformative interview segments that rivers also have waves, which quickly gets repetitive. Fortunately, the film also profusely illustrates the point with some remarkably vivid video footage originally shot by Lob and co-cinematographer Lars Liebold, on a variety of formats. The visual clarity of these scenes is truly quite stunning. Every move the surfers make are clearly distinct, yet the sequences have an up-close immediacy that is thoroughly impressive. From a technical standpoint, Lob dramatically ups the ante for surfing films, far surpassing the cult classics of Bruce Brown (whose early films are still worth checking out for the Bud Shank jazz soundtracks).
