Arne Sucksdorff’s debut—made when he was 23— is a lyrical short about Sweden’s late-summer crayfish fishery: night-time trapping on water, daybreak on the shore, and the rhythms of August nature rendered in carefully composed images. Often grouped with This Land Is Full of Life as one of Sucksdorff’s “hymns to the Swedish summer,” the film distills a 24-hour cycle into a seven-minute nature rhapsody.
