A member of Haywards Heath Cine Society films the two-man crabber teams at work off the Cornish coast at Coverack. Their hauls of shellfish are purchased by the Newlyn-based 'W. Harvey & Sons Shellfish Merchants', and are deshelled by female workers.

D J Church's film begins with a garden tea party, with crab sandwiches on the menu. Next the film moves to Coverack in Cornwall to see the Crabbers in action; preparing their boats, retrieving storepots and unloading their substantial catch into baskets. Full baskets of edible crabs and lobsters are loaded onto the quayside and weighed. The catch is loaded onto a truck from Newlyn and taken away. Women separate the crab meat from the shells and the film ends back at the tea party.
