Motoring past lighthouse. 'At dusk the fishers play out their nets, for with the fading light these become invisible to the fish'. Close up view of fishermen lettering out nets. 'The fleet drifts gently through the night, as the men labour - casting and recasting - until the dawn brings their toil to an end.' Bringing in haul.
