Shoreline images: first small breakers and the swirls they leave, then water running up the shore on a sandy beech, then water hitting pebbles and rocks. The second half is a close look at a sluggish eddy of seaweed, moving to and fro on the surface, like sodden twigs. The ocean's tide creates patterns of small surges and circles. The music of the soundtrack is more dramatic than the more gentle movements of the seaweed. Final closeups show the bulbs and leaves of the plants, then the tide takes over.
